wc820/aa9 is probably my most used powder. I started buying it because of the cost but now would buy it even if it werent cheaper. Alot of my most accurate loads in everything from the 32s to the 500 linebaugh are with it. Just down download it much and for the most part use a mag primer and it works great. my go to load in the 500 is 27 grains with a 440 lfn and a cci 350. It is very accurate in both of my 500s

Looking to see what powders were availalble to work up loads for my 500L. Got Blue Dot and H110 on the shelf... Thinking I needed some 2400 or H4227 but it was all on order. Saw some AA #9 so I looked at the Accurate manual for 500L loads.... Any of you guys getting good results with #9 in your 500L?

For anyone that uses AA#9 this is a helluva deal for 8lbs of WC820 ($80) which is basically the same stuff.

.500 Linebaugh Primer Test

The Author & Leverguns.Com will not be held liable for any problems such a person may encounter. The Author states that these loads were safe in his gun and his gun only.
This small article will not cover the origin of the John Linebaugh’s .500, as that has been covered very well by others. If interested in the background, I recommend Taffin Tests: The .500 Linebaugh by John Taffin.
One of the first things a shooter will discover about the .500L is a dearth of clean-burning light-to-medium loads that bulk well. In 454s, WC680 (a military surplus powder similar to AA1680) is utilized volume-to-volume with WC820 (a military surplus powder similar to 296/110) for a reduced load (usually about 2-300fps less). This allows a high load density for the powder, preventing the possibility of a double charge. Personally, I just wasn’t comfortable using a faster powder at something like 30% load density – particularly since all my ammo is loaded on a Dillon 550.
However, the next discovery was that the cavernous .500L case did not lend itself to the same volume-to-volume relationship between WC820/WC680 that worked so well in the 454s. Thirty grains of WC680 behind the excellent 440gr Cast Performance bullet did not burn well at all – worse yet, variation in the recoil impulse shot-to-shot was noticed, which indicated LARGE extreme spreads. Back to the drawing board.
Quickload was queried, and it calculated the above-mentioned load of 30grs WC680 beneath the 440gr CP bullet crimped in the groove from my 4&5/8” barrel should yield 68% case fill and 877fps. The crimp bears mentioning, as a good heavy crimp is necessary for any heavy bullet load, especially with slower powders. The Dillon is set up with a modified powder funnel (.005” reduction in diameter) so as to not over expand the case. Dies are Hornady with seating/crimping done in separate steps.
Since the .500L originated from .348 Winchester rifle brass, investigating the primer pockets of the Buffalo Bore Ammunition .500L brass seemed logical – YES, they will accept rifle primers without problems. Now to find out if the custom Ruger 5-shot could overcome the harder rifle primer cups. Inventorying the reloading area for primers yielded six different manufacturers represented in large pistol flavor and eight in large rifle. Utilizing new, never fired BBA brass, 30grs of WC680 entombed beneath a 440gr bullet, changing nothing except primers, I proceeded with the test. Five shot string data below, with the following definitions: Avg. = average velocity, Std. Dev. = standard deviation, E.S. = extreme spread, and Avg. Exp. = average case expansion. Case expansion, measured just above the rim, is Ken Water’s method of comparing pressures of various loads in the same gun. Barrel and chambers were swabbed with several patches between each string.

CCI is not kidding when they say these primers are tough! Two required a second strike to ignite, the only primer in this series to defeat the Bisley's stock mainspring. Large E.S. probably attributable to marginal firing pin hits. Unusable, obviously - unless you want to check your flinch.

Respectable performance while delivering an average velocity closest to Quickload's prediction. Neither here nor there, of course. Another interesting primer that will see more testing.
Notice the wide swing in velocity; WC680 is rather slow for the .500L, but will turn in respectable results if close attention is paid to primer selection. This is true of both pistol and rifle primers. It must be mentioned that the poor showing of some of the pistol primers in this test does not mean they will not work as their manufacturer intended; i.e., in normal pistol cases with faster powders.
The following day, one hundred rounds of the above load were fired. Fifty rounds were primed with CCI 250 primers and fifty rounds with the Federal 215 primer. Disappointingly, there were three failure-to-fires (FTF) with the CCI 250 primers. No doubt the mainspring is not up to the task of igniting the hard CCI rifle primer. No problems at all with the Federal 215 loads. Both loads put down the six-inch falling plates from the fifty-yard line with alacrity. No surprise there as the IPSC Power Factor for the Federal 215 load (440gr @ 977fps) is 430…
No attempt was made to shoot these variations for groups during this test, preferring to cull a few of the underachievers via the chronograph. Also, a plain-base 480gr Whitworth mold has been obtained from Mountain Molds it was expressly designed to displace more internal volume than the Cast Performance 440gr bullet, so it should prove even better suited to the reduced load task.
In conclusion, and at this point, WC680 or it's commercial twin Accurate Arms 1680 appears to be a viable powder when rifle primers are utilized for the .500L pending accuracy testing. It certainly fits the requirement of preventing a possible double charge while providing a light-to-medium practice load.

TAFFIN TESTS: THE .500 LINEBAUGH
by JOHN TAFFIN
In 1935, Smith & Wesson brought forth the first Magnum sixgun and cartridge combination, the .357 Magnum. It was hailed as "The World's Most Powerful" based on its 158 grain .38 caliber bullet at 1400+ feet per second. Elmer Keith, testing it for the American Rifleman that year, came to the conclusion that paper ballistics to the contrary, his .44 Special loads of 250 grain bullets at 1200 feet per second were really the world's most powerful.
By 1956, Keith and like-minded sixgunners finally convinced Smith & Wesson to correct their original mistake and really bring out the world's most powerful gun and cartridge combination and the .44 Magnum was born. Now we really had the true world's most powerful and everyone would be satisfied. Right? Wrong!
Dick Casull had been working with magnumizing the .45 Colt from the early 1950's and the introduction of the .44 Magnum did not detract him one bit on his way to the true world's most powerful. His continued experiments finally resulted in the factory production of the real world's most powerful cartridge and revolver in 1983 as the .454 Casull took over the title. Surely, we had now reached the pinnacle of power and the quest was ended. Wrong again.
In the early 1980's, a young gunsmith in Cody, Wyoming began experimenting with the .45 Colt in custom sixguns and decided more was needed. To John Linebaugh, three things were important in a cartridge and those three things were caliber, caliber, and caliber. Bigger is better, and heavier, fatter bullets would allow handgun hunters to take those difficult angling shots knowing that the heavy bullet would deliver needed penetration.
While Keith and Casull had the .44 Special and .45 Colt to work with, Linebaugh had no handgun cartridge case to use. A quick look at the dimensions of rifle brass yielded the perfect candidate for his .50 caliber cartridge. The old .348 Winchester measures .535" in diameter at the base tapering to .485" at the shoulder 1.630" away and the rim thickness is a revolver usable .070". The .50 caliber revolver cartridge was a wildcat reality.
Settling on a length of 1.410", Linebaugh trimmed .348 Winchester brass to length, reamed the inside of the newly formed neck and the .500 Linebaugh was born, albeit also known as the .50 Magnum and .51 Magnum along the way. Factory brass is now headstamped ".500 Linebaugh" and is generally available, along with .500 revolvers, from Linebaugh Custom Guns (PO Box 1263, Dept AH, Cody Wyoming 82414. Phone 307-645-3162.)
Early .500's were built on both Seville and Ruger Super Blackhawk Single Actions, but all current .500's built by Linebaugh are on the Ruger Bisley. The .500 is also available from Bowen Classic Arms (PO Box 67, Dept AH, Louisville Tennessee 37777. Phone 615-984-3583) on either the Bisley or the Redhawk.
The .500 Linebaugh offers the shooter a five-shot revolver that utilizes 400 to 440 grain bullets of .51 caliber at velocities approaching 1300 feet per second. Reloading is easily accomplished using RCBS dies which are available from the RCBS Custom Shop. Loading is easy; case forming is not. The best way to go is to purchase .500 Linebaugh brass from Buffalo Bore. If one chooses to do-it-yourself, .348 Winchester to .500 Linebaugh case forming dies are available from RCBS that provide for trimming to length and inside neck reaming.
Bullets for the .500 are have been available in the form of excellent double cavity moulds from either LBT and are still so from NEI. LBT offered a 400 grain bullet in their #512.400LFN and 440 grain #512.440LFN, LFN standing for Long Flat Nose. NEI's offering is #420.511, a 440 grain Keith style bullet.
For those that do not cast their own, two sources of cast bullets are available to my knowledge: Cast Performance Bullet Co. has LBT designs and BRP has the NEI .440 grain Keith bullet in their lineup of hard cast bullets.
In working with the .500 Linebaugh, I use both the 400 and 440 grain LBT bullets as well as the NEI 440 grain Keith semi- wadcutter. All bullets are cast hard with three parts lead to four parts type metal and are sized at .512". They slip through the RCBS sizing die very easily as these bullets are designed for minimum sizing.
Casting bullets for the big .500 requires a lot of molten alloy as I run two double cavity moulds at the same time and they empty the Lyman Mag 20 melting pot quickly. Patience is also required as it takes extra time for the sprue to harden on these large bullets. One could easily run three moulds at the same time to avoid waiting time for cooling.
Recoil for the .500 is heavy once 400 grain bullets exceed 1200 feet per second and 440's go over 1100 feet per second. If one is a seasoned sixgunner along the lines of the .44 Magnum or .454 Casull, the .500 should be manageable with practice and working up to the top loads. Mathematically speaking, full house loads from either the .454 Casull or .500 Linebaugh recoil twice as much as .44 Magnum loads. This is not felt recoil and does not take into account grip shape, shooter attitude, etc.
Top loads for the .500 are normally achieved with WW 296 and proper primer choice is absolutely critical. I have found only one primer that will ignite these large doses of WW296 in cold weather and that is CCI's #350 Magnum Pistol Primer. Other pistol primers tried resulted in bullets stuck in the barrel, large amounts of unburned powder clogging both barrel and cylinder and one memorable round that read a whopping 90 feet per second over my Oehler Model 35P.
For use in cold weather, I would forgo WW296, normally one of my favorite powders, and stay with #2400, Blue Dot, and H4227. All of these seem much easier to ignite in the big .500 case when the temperature drops.
Favorite loads for the .500 include the LBT 400 grain bullet over 10.0 grains of WW231 for a very pleasant shooting 850+ foot per second practice load, and this is the type of load that the majority of shooting with the .500 should consist of. For the heavier 440 grain bullets, I drop the charge one grain and still get 800 feet per second. These may be labeled "practice" loads, but 400 to 440 grain bullets at 800 feet per second could still be very practical close range deer hunting loads. Moving up the line to 900 to 1000 feet per second, 26.0 grains of H4227 or 21.0 to 22.0 grains of #2400 gives excellent results.
For full power loadings in the 1100-1300 feet per second range, the 400 grainer performs the highest velocities for me with 31.0 grains of WW296 for 1201 fps and 28.0 grains of #2400 for 1277 fps. Recoil is starting to get stout at this level.
The .500 really sits up and sings with the 440 grain bullets as this seems to be the optimum weight for case capacity and bore diameter. LBT's 440 grain bullet goes 1171 fps with 29.0 grains of WW296, 1179 fps with 26.0 grains of #2400, and 1123 fps with 20.0 grains of Blue Dot. All velocities are measured from a five and one-half inch barreled Bisley .500.
Switching to NEI's beautiful 440 grain Keith bullet, 29.0 grains of WW296 gives 1256 feet per second, and for a little less recoil but still plenty of power, 28.0 grains of H4227 comes in at 1102 fps, and 25.0 grains of #2400 gives 1114 fps. All of these velocities may sound mild to those used to .357 Magnum, .41 Magnum, and .44 Magnum velocities but remember we are talking 440 grain bullets compared to
158, 210, and 240 grain bullets respectively with the standard Magnum offerings.
What does the .500 offer to the shooter? It is not a silhouette gun. It is not a target gun by any means. It is certainly not what is usually thought of as a personal defensive weapon. It is pure and simple a hunting handgun and if one was suddenly faced with an angry lion or big bear, I could think of no other handgun I would rather have in my hand than a .500 Linebaugh Bisley.
Linebaugh's philosophy in building handguns is to offer power, practicality, and portability. As he says: "a handgun that can be carried comfortably on the hip all day and easily placed under a pillow or bedroll at night" In the .500, Linebaugh has reached the outer limits of power combined with practicality and portability. I'm almost ready to say that the ultimate most powerful revolver has finally been attained, but I know if I do I will find someone out there that is working on some future contender. For right now at least, the .500 is King.

500 Linebaugh
Historical Notes:
The 500 Linebaugh is the design creation of John Linebaugh, of Maryville, MO. John started out by converting a 45 Colt revolver from a 6 shot to a 5 shot, thus offering more strength in the cylinder. It was a successful venture, but John continued to search for a more powerful handgun. The result is the 500 Linebaugh. The 500 Linebaugh is based on the 348 Winchester cartridge cut down to 1.5 inches and inside reamed to 500 caliber. John uses a large frame Ruger Bisley revolver as he found the Ruger frame is the only one that can withstands the sever recoil of this cartridge. He replaces the Ruger barrel with one of 50 caliber, usually 5.5 inches long. However, he will cut a barrel of any length that the customer desires. The 500 proved to be a very successful round pushing 500 grain bullets over 1200 fps. Accuracy is outstanding, but recoil can only be described as severe. Not long after John designed this cartridge, the supply of 348 Winchester brass began to dry up which is why John designed the 475 Linebaugh based on the readily available 45-70 Government case. Not long after the 475 was designed, Browning reintroduced their Model 1871 rifle in 348 Winchester, and those cases are again readily available.
General Comments:
There are more powerful pistol cartridges, but for single shot handguns such as the Thompson/Center Contender. When it comes to the revolver, this is close to the ultimate in power. Due to its accuracy and easily handling, this cartridge could prove to be an excellent heavy game handgun cartridge and possibly the revolver cartridge suitable for taking African game. Specialized bullets are made by Golden Bear of San Jose, CA. The jackets for these are turned on a screw machine and a lead core is swaged in. These bullets have been found to be excellent performers both in terms of accuracy and penetration. The 500 Linebaugh should find a strong following in the wilds of Alaska or the plains of Africa, where it could be used as a primary hunting gun or a backup.

wc820/aa9 is probably my most used powder. I started buying it because of the cost but now would buy it even if it werent cheaper. Alot of my most accurate loads in everything from the 32s to the 500 linebaugh are with it. Just down download it much and for the most part use a mag primer and it works great. my go to load in the 500 is 27 grains with a 440 lfn and a cci 350. It is very accurate in both of my 500s

Looking to see what powders were availalble to work up loads for my 500L. Got Blue Dot and H110 on the shelf... Thinking I needed some 2400 or H4227 but it was all on order. Saw some AA #9 so I looked at the Accurate manual for 500L loads.... Any of you guys getting good results with #9 in your 500L?

For anyone that uses AA#9 this is a helluva deal for 8lbs of WC820 ($80) which is basically the same stuff.

.500 Linebaugh Primer Test
Note: This article is for information purposes only. Anyone who uses any reloading data contained herein does so at their own risk. The Author & Leverguns.Com will not be held liable for any problems such a person may encounter. The Author states that these loads were safe in his gun and his gun only.
This small article will not cover the origin of the John Linebaugh’s .500, as that has been covered very well by others. If interested in the background, I recommend Taffin Tests: The .500 Linebaugh by John Taffin.
One of the first things a shooter will discover about the .500L is a dearth of clean-burning light-to-medium loads that bulk well. In 454s, WC680 (a military surplus powder similar to AA1680) is utilized volume-to-volume with WC820 (a military surplus powder similar to 296/110) for a reduced load (usually about 2-300fps less). This allows a high load density for the powder, preventing the possibility of a double charge. Personally, I just wasn’t comfortable using a faster powder at something like 30% load density – particularly since all my ammo is loaded on a Dillon 550.
However, the next discovery was that the cavernous .500L case did not lend itself to the same volume-to-volume relationship between WC820/WC680 that worked so well in the 454s. Thirty grains of WC680 behind the excellent 440gr Cast Performance bullet did not burn well at all – worse yet, variation in the recoil impulse shot-to-shot was noticed, which indicated LARGE extreme spreads. Back to the drawing board.
Quickload was queried, and it calculated the above-mentioned load of 30grs WC680 beneath the 440gr CP bullet crimped in the groove from my 4&5/8” barrel should yield 68% case fill and 877fps. The crimp bears mentioning, as a good heavy crimp is necessary for any heavy bullet load, especially with slower powders. The Dillon is set up with a modified powder funnel (.005” reduction in diameter) so as to not over expand the case. Dies are Hornady with seating/crimping done in separate steps.
Since the .500L originated from .348 Winchester rifle brass, investigating the primer pockets of the Buffalo Bore Ammunition .500L brass seemed logical – YES, they will accept rifle primers without problems. Now to find out if the custom Ruger 5-shot could overcome the harder rifle primer cups. Inventorying the reloading area for primers yielded six different manufacturers represented in large pistol flavor and eight in large rifle. Utilizing new, never fired BBA brass, 30grs of WC680 entombed beneath a 440gr bullet, changing nothing except primers, I proceeded with the test. Five shot string data below, with the following definitions: Avg. = average velocity, Std. Dev. = standard deviation, E.S. = extreme spread, and Avg. Exp. = average case expansion. Case expansion, measured just above the rim, is Ken Water’s method of comparing pressures of various loads in the same gun. Barrel and chambers were swabbed with several patches between each string.

CCI is not kidding when they say these primers are tough! Two required a second strike to ignite, the only primer in this series to defeat the Bisley's stock mainspring. Large E.S. probably attributable to marginal firing pin hits. Unusable, obviously - unless you want to check your flinch.

Respectable performance while delivering an average velocity closest to Quickload's prediction. Neither here nor there, of course. Another interesting primer that will see more testing.
Notice the wide swing in velocity; WC680 is rather slow for the .500L, but will turn in respectable results if close attention is paid to primer selection. This is true of both pistol and rifle primers. It must be mentioned that the poor showing of some of the pistol primers in this test does not mean they will not work as their manufacturer intended; i.e., in normal pistol cases with faster powders.
The following day, one hundred rounds of the above load were fired. Fifty rounds were primed with CCI 250 primers and fifty rounds with the Federal 215 primer. Disappointingly, there were three failure-to-fires (FTF) with the CCI 250 primers. No doubt the mainspring is not up to the task of igniting the hard CCI rifle primer. No problems at all with the Federal 215 loads. Both loads put down the six-inch falling plates from the fifty-yard line with alacrity. No surprise there as the IPSC Power Factor for the Federal 215 load (440gr @ 977fps) is 430…
No attempt was made to shoot these variations for groups during this test, preferring to cull a few of the underachievers via the chronograph. Also, a plain-base 480gr Whitworth mold has been obtained from Mountain Molds it was expressly designed to displace more internal volume than the Cast Performance 440gr bullet, so it should prove even better suited to the reduced load task.
In conclusion, and at this point, WC680 or it's commercial twin Accurate Arms 1680 appears to be a viable powder when rifle primers are utilized for the .500L pending accuracy testing. It certainly fits the requirement of preventing a possible double charge while providing a light-to-medium practice load.

TAFFIN TESTS: THE .500 LINEBAUGH
by JOHN TAFFIN
In 1935, Smith & Wesson brought forth the first Magnum sixgun and cartridge combination, the .357 Magnum. It was hailed as "The World's Most Powerful" based on its 158 grain .38 caliber bullet at 1400+ feet per second. Elmer Keith, testing it for the American Rifleman that year, came to the conclusion that paper ballistics to the contrary, his .44 Special loads of 250 grain bullets at 1200 feet per second were really the world's most powerful.
By 1956, Keith and like-minded sixgunners finally convinced Smith & Wesson to correct their original mistake and really bring out the world's most powerful gun and cartridge combination and the .44 Magnum was born. Now we really had the true world's most powerful and everyone would be satisfied. Right? Wrong!
Dick Casull had been working with magnumizing the .45 Colt from the early 1950's and the introduction of the .44 Magnum did not detract him one bit on his way to the true world's most powerful. His continued experiments finally resulted in the factory production of the real world's most powerful cartridge and revolver in 1983 as the .454 Casull took over the title. Surely, we had now reached the pinnacle of power and the quest was ended. Wrong again.
In the early 1980's, a young gunsmith in Cody, Wyoming began experimenting with the .45 Colt in custom sixguns and decided more was needed. To John Linebaugh, three things were important in a cartridge and those three things were caliber, caliber, and caliber. Bigger is better, and heavier, fatter bullets would allow handgun hunters to take those difficult angling shots knowing that the heavy bullet would deliver needed penetration.
While Keith and Casull had the .44 Special and .45 Colt to work with, Linebaugh had no handgun cartridge case to use. A quick look at the dimensions of rifle brass yielded the perfect candidate for his .50 caliber cartridge. The old .348 Winchester measures .535" in diameter at the base tapering to .485" at the shoulder 1.630" away and the rim thickness is a revolver usable .070". The .50 caliber revolver cartridge was a wildcat reality.
Settling on a length of 1.410", Linebaugh trimmed .348 Winchester brass to length, reamed the inside of the newly formed neck and the .500 Linebaugh was born, albeit also known as the .50 Magnum and .51 Magnum along the way. Factory brass is now headstamped ".500 Linebaugh" and is generally available, along with .500 revolvers, from Linebaugh Custom Guns (PO Box 1263, Dept AH, Cody Wyoming 82414. Phone 307-645-3162.)
Early .500's were built on both Seville and Ruger Super Blackhawk Single Actions, but all current .500's built by Linebaugh are on the Ruger Bisley. The .500 is also available from Bowen Classic Arms (PO Box 67, Dept AH, Louisville Tennessee 37777. Phone 615-984-3583) on either the Bisley or the Redhawk.
The .500 Linebaugh offers the shooter a five-shot revolver that utilizes 400 to 440 grain bullets of .51 caliber at velocities approaching 1300 feet per second. Reloading is easily accomplished using RCBS dies which are available from the RCBS Custom Shop. Loading is easy; case forming is not. The best way to go is to purchase .500 Linebaugh brass from Buffalo Bore. If one chooses to do-it-yourself, .348 Winchester to .500 Linebaugh case forming dies are available from RCBS that provide for trimming to length and inside neck reaming.
Bullets for the .500 are have been available in the form of excellent double cavity moulds from either LBT and are still so from NEI. LBT offered a 400 grain bullet in their #512.400LFN and 440 grain #512.440LFN, LFN standing for Long Flat Nose. NEI's offering is #420.511, a 440 grain Keith style bullet.
For those that do not cast their own, two sources of cast bullets are available to my knowledge: Cast Performance Bullet Co. has LBT designs and BRP has the NEI .440 grain Keith bullet in their lineup of hard cast bullets.
In working with the .500 Linebaugh, I use both the 400 and 440 grain LBT bullets as well as the NEI 440 grain Keith semi- wadcutter. All bullets are cast hard with three parts lead to four parts type metal and are sized at .512". They slip through the RCBS sizing die very easily as these bullets are designed for minimum sizing.
Casting bullets for the big .500 requires a lot of molten alloy as I run two double cavity moulds at the same time and they empty the Lyman Mag 20 melting pot quickly. Patience is also required as it takes extra time for the sprue to harden on these large bullets. One could easily run three moulds at the same time to avoid waiting time for cooling.
Recoil for the .500 is heavy once 400 grain bullets exceed 1200 feet per second and 440's go over 1100 feet per second. If one is a seasoned sixgunner along the lines of the .44 Magnum or .454 Casull, the .500 should be manageable with practice and working up to the top loads. Mathematically speaking, full house loads from either the .454 Casull or .500 Linebaugh recoil twice as much as .44 Magnum loads. This is not felt recoil and does not take into account grip shape, shooter attitude, etc.
Top loads for the .500 are normally achieved with WW 296 and proper primer choice is absolutely critical. I have found only one primer that will ignite these large doses of WW296 in cold weather and that is CCI's #350 Magnum Pistol Primer. Other pistol primers tried resulted in bullets stuck in the barrel, large amounts of unburned powder clogging both barrel and cylinder and one memorable round that read a whopping 90 feet per second over my Oehler Model 35P.
For use in cold weather, I would forgo WW296, normally one of my favorite powders, and stay with #2400, Blue Dot, and H4227. All of these seem much easier to ignite in the big .500 case when the temperature drops.
Favorite loads for the .500 include the LBT 400 grain bullet over 10.0 grains of WW231 for a very pleasant shooting 850+ foot per second practice load, and this is the type of load that the majority of shooting with the .500 should consist of. For the heavier 440 grain bullets, I drop the charge one grain and still get 800 feet per second. These may be labeled "practice" loads, but 400 to 440 grain bullets at 800 feet per second could still be very practical close range deer hunting loads. Moving up the line to 900 to 1000 feet per second, 26.0 grains of H4227 or 21.0 to 22.0 grains of #2400 gives excellent results.
For full power loadings in the 1100-1300 feet per second range, the 400 grainer performs the highest velocities for me with 31.0 grains of WW296 for 1201 fps and 28.0 grains of #2400 for 1277 fps. Recoil is starting to get stout at this level.
The .500 really sits up and sings with the 440 grain bullets as this seems to be the optimum weight for case capacity and bore diameter. LBT's 440 grain bullet goes 1171 fps with 29.0 grains of WW296, 1179 fps with 26.0 grains of #2400, and 1123 fps with 20.0 grains of Blue Dot. All velocities are measured from a five and one-half inch barreled Bisley .500.
Switching to NEI's beautiful 440 grain Keith bullet, 29.0 grains of WW296 gives 1256 feet per second, and for a little less recoil but still plenty of power, 28.0 grains of H4227 comes in at 1102 fps, and 25.0 grains of #2400 gives 1114 fps. All of these velocities may sound mild to those used to .357 Magnum, .41 Magnum, and .44 Magnum velocities but remember we are talking 440 grain bullets compared to
158, 210, and 240 grain bullets respectively with the standard Magnum offerings.
What does the .500 offer to the shooter? It is not a silhouette gun. It is not a target gun by any means. It is certainly not what is usually thought of as a personal defensive weapon. It is pure and simple a hunting handgun and if one was suddenly faced with an angry lion or big bear, I could think of no other handgun I would rather have in my hand than a .500 Linebaugh Bisley.
Linebaugh's philosophy in building handguns is to offer power, practicality, and portability. As he says: "a handgun that can be carried comfortably on the hip all day and easily placed under a pillow or bedroll at night" In the .500, Linebaugh has reached the outer limits of power combined with practicality and portability. I'm almost ready to say that the ultimate most powerful revolver has finally been attained, but I know if I do I will find someone out there that is working on some future contender. For right now at least, the .500 is King.

500 Linebaugh
Historical Notes:
The 500 Linebaugh is the design creation of John Linebaugh, of Maryville, MO. John started out by converting a 45 Colt revolver from a 6 shot to a 5 shot, thus offering more strength in the cylinder. It was a successful venture, but John continued to search for a more powerful handgun. The result is the 500 Linebaugh. The 500 Linebaugh is based on the 348 Winchester cartridge cut down to 1.5 inches and inside reamed to 500 caliber. John uses a large frame Ruger Bisley revolver as he found the Ruger frame is the only one that can withstands the sever recoil of this cartridge. He replaces the Ruger barrel with one of 50 caliber, usually 5.5 inches long. However, he will cut a barrel of any length that the customer desires. The 500 proved to be a very successful round pushing 500 grain bullets over 1200 fps. Accuracy is outstanding, but recoil can only be described as severe. Not long after John designed this cartridge, the supply of 348 Winchester brass began to dry up which is why John designed the 475 Linebaugh based on the readily available 45-70 Government case. Not long after the 475 was designed, Browning reintroduced their Model 1871 rifle in 348 Winchester, and those cases are again readily available.
General Comments:
There are more powerful pistol cartridges, but for single shot handguns such as the Thompson/Center Contender. When it comes to the revolver, this is close to the ultimate in power. Due to its accuracy and easily handling, this cartridge could prove to be an excellent heavy game handgun cartridge and possibly the revolver cartridge suitable for taking African game. Specialized bullets are made by Golden Bear of San Jose, CA. The jackets for these are turned on a screw machine and a lead core is swaged in. These bullets have been found to be excellent performers both in terms of accuracy and penetration. The 500 Linebaugh should find a strong following in the wilds of Alaska or the plains of Africa, where it could be used as a primary hunting gun or a backup.
