I removed my cylinder from my Clements 45 colt blackhawk and discovered a concerning situation. I'm no expert but looks like I'm having pretty serious erosion of barrel face? I've shot this gun a lot. Probably 4k+ loads mostly standard pressure but for the past year have been using Brian pearces mid level loads with Longshot. Probably 3-400 of them so far. My poor barrel! This is my favorite gun. What are your experiences with this condition? My s&w model 53 22 jet has much more advanced erosion and shoots great. I have not experienced any drop in accuracy with this gun either. Cry cry cry.  |

Your good photo shows erosion that doesn’t rise to the dignity of minor. David Bradshaw |

LOL. Your diagnosis has me standing tall.

If you are concerned about it stop using Longshot.

If you are concerned about it stop using Longshot. Maybe it's not longshot causing? Maybe it's something else? I've shot up a 15 lb metal keg of herco over the past 3 years. Maybe that 50+ year old powder is doing it? Maybe it's the metal composition of Clements custom barrel? I'm more interested in others experiences with the powder than just dropping it. Longshot has been by far my most accurate powder from the start of trying it. |

If I'm not mistaken Freedom Arms as advised using Longshot in their sixguns.

Cannot tell from photo whether Blackhawk is blue or stainless. A stainless barrel shows barrel face erosion more slowly. However, as I took a closer look, the formation of rivulets on the edge of the forcing cone are, to this shooter, characteristic of aggressive heat and/or particle abrasion during combustion.
Don’t know whether laziness or timidity may cause a shooter to withhold exact load data from technical discussions. When you’re on the information trail, every little bit helps.
Reducing powder charge 1 grain, or so, and DEEP SEATING, may hold peak pressure rearward and reduce sideblast. I have long thought ball powders spew abrasive particles during combustion. Nitroglycerine produces a lot of hot energy; double base ball powders have nitroglycerine added to nitrocellulose. To this shooter, ball powders seemed to erode the forward cage of flash hiders on .223 machine guns.
A for the .22 Jet, barrel face, and/or forcing cone, is doomed to erode faster than a big bore. And, yes, while erosion should not affect accuracy, it opens the door to spitting, especially in the presence of chamber-to-bore misalignment.
On carbon steel revolver .44 Mag barrels, erosion of the barrel face by Hercules 2400 was smooth, pretty much devoid of rivulets.
None of which will stop me from shooting Winchester 296 and its re-label Hodgdon H110 at magnum levels in blue, as well as stainless, revolvers.

^^^^^^^^^^^^^^ Good advice. Find some Unique and you won't have a question on that anymore.

I've been shooting 11.2 grains longshot behind PC lead
Mp 308k solid weighs 306g
Mp 45 carbine deep hp 265g
Mp 270saa solid 285g
Shoot the 3 above bullets with
9.2g old herco
10g old herco
Shoot lee 255 rf and noe 255 swc with
7.2g w231
6.5g red dot
I've used Winchester LP, cci 300. The last few thousand have been loaded using old Alcan large pistol primers that have proven reliable and accurate.
98% of my shooting is these 5 bullets and loads. All crimped in crimp grooves.been fired in between 12 ruger single actions and 3 different lever rifles. All fired only by me. All powder coated. All sized trough the same lee .452 push through sizer.all cast from the same lee bottom pour pot. My lead is a mix of range scrap and old wheel weights. Powder coated should even out most variables. They Shoot accurately.
The barrel shown is a custom stainless nimrod type barrel from David Clements. The stainless vaquero I have from him wears a factory barrel and does not have the issue. I've fired my other guns only 1/2 as much at most as I have this one.

Bob Baker told me never to use Lil Gun in Revolvers Period. I took him at his word and don't... At your advice, and it has borne out in performance, my 8 lb jug of lil gun only sees use in pistol caliber carbines. For that it can't be beat. I've not heard of longshot being a culprit in premature barrel wear, but it's possible I suppose and maybe even lot dependent. The next issue with Clements (and Gallagher and Stroh) guns are which smiths will set a barrel back on another custom maker's work? |

I've not heard of longshot being a culprit in premature barrel wear, but it's possible I suppose and maybe even lot dependent. The next issue with Clements (and Gallagher and Stroh) guns are which smiths will set a barrel back on another custom maker's work? Exactly. I'm not experiencing issues yet but if the deterioration continues or even increases it will be. I don't want to park this gun. But at some point it will be finished. The barrel band makes a real problem for setting a barrel back. Most smiths will not tough another's work. I think I'm going to stop with my longshot loads. I have another 4 lb jug of more recent herco. I've been shooting some of the 8lb jug of red dot I bought new last year and I have a few pounds of recent w231 and bullseye. I shot up my unique and because I had a bunch of old powder or couldn't find locally have not replenished. Maybe I will just focus on my standard loads with red dot and w231 and see what happens. This is the only one of my guns showing these signs. Only one other of mine has a custom barrel, im not sure whose blanks John Powers uses. 1 has a s&w barrel, but the rest have factory ruger barrels. |
