Didn't make to Redstone until '89. Only 58 years old now so the Saturn V was a little before my adult working years. Have heard tales from the locals about how the entire world would shake when the Saturn Vs were fired on the test stands... Did arrive in Huntsville before the solid rocket motors and their testing went to Utah.. Not earth shaking but nothing like the sound of a solid fuel rocket motor firing..

Pounds of thrust needed:
Yeager, speed of sound. 16 K X-15, small engine. 32 K X-15, large engine. 78 K Al Shepard, up and down 78 K John Glenn, orbit 365 K Shuttle 1200 K Sarturn V. 7500 K
The fuel pump for each of the 5 engines in the Saturn was 55,000 HP!!
Total the fuel pumps and you have the HP of an Iowa class Battleship. Yup the ones with 9 16 inch 50 caliber guns.
The test stand at Redstone was designed for 12,000,000 lbs of thrust. A 70 foot jib crane with a 200 ton lift set things up. Before a test, 8 water tanks were filled. During the test, 8 pumps were feeding the base for cooling, each with 3000 HP
It was a great time.
There are utube videos on it now.
During a launch, the engines were fired and about 14 seconds later the hold down charges are touched off and the Saturn launches. To touch off the charges??
3 Winchester primers on each one!
Sorry for rambling.......Redstone was greatm

Enjoyed that ramble! I was a jr hi kid living in Huntsville in the early '70's. My dad was an Army Missile Command officer and all that rocket stuff was really impressive.
Three little Winchester primers.... wow

Princeout; Did you stay around for the tornado in 74?

No. The whole idea of trying to push any given caliber or gun to excessive overload levels "to see what it can really do" strikes me as idiocy, and has for years. I agree! If you want .454 performance, buy a .454 not a .45 Colt and hot rod it.

Don't know much but after 35+ years of DoD and NASA Research & Development and Production... I've been exposed to a little metalugy and NDT/NDI/NDE stuff. I've even seen a little destructive testing through the years.. Bottom line... IMHO in this specific context, other than fuel for argument, all this is so much noise. It just doesn't matter.. I'm not a rocket scientist, but I did stay a at a Holiday inn express last night, really, (in Helena, Montana) Its funny how many single action guys here have aviation backgrounds, I was an A&P line mechanic years ago. How did this thread become about who's gun is stronger anyway? Seems like the 454 has been pushed pretty hard and I was only wondering if anyone had pushed there FAs 83 a little to hard.

Aciera, We left in the summer of '72 - moved to Oklahoma for a better chance at tornadoes. Tim

princeout; Fort Sill and the Artillery School?
One thing about the tornado, everything that we were short on got lost or destroyed in the tornado.

Were all the failures to the OD of the cylinder? Were any chamber to chamber? The damage was a flat to the outside of the cylinder indicating it hit the top strap. I incorrectly used the term "bulged" earlier

They were not misloaded and the Freedom gave at a lower pressure while the BFR showed no measurable damage -- again, at higher pressure. The results can't be disputed, they are what they are. From inside the cylinder to the outside of the cylinder, the FA is about .010-inch thicker than the BFR. From cylinder hole to cylinder hole, the BFR is about .035-inch thicker -- by my measurements. I never claimed that one was better than the other -- go back and read my post. I said they were different. They are what they are. Actually, the JRH has been available for years through the Precision Center -- mine is from the Precision Center. They will become a regular production, over-the-counter caliber soon and retail for considerably less. You keep referring to the pressures, but do not list the pressures. Also, by whom were these cartridges tested for pressure. Pressure varies in regard to the chamber in which the cartridge is fired. If the pressure testing was not done in a chamber which is identical to the firearm's particular chamber, then the pressure will not be the same. When the 500WE was brand new, I had no data upon which to refer, and tried to push the cartridge/gun to the limit. I loaded a 525 to over 1700 fps, clocked from the 7.5 inch barrel at a distance of twelve feet. Way over pressure, i am certain, and i will not try that again, but the gun held together just fine. That same bullet at 1325 is a much better load, and works well, with normal extraction. I know that both the BFR and the FA are good weapons, and quality built, but without qualified pressure data that is relative to the exact chamber specs of each revolver, comparison is meaningless, and concluding that one is superior in strength to the other is merely speculation.

"525 to over 1700 fps, clocked from the 7.5 inch barrel at a distance of twelve feet" in a 50oz gun! That hurts my hand just reading about it!

"525 to over 1700 fps, clocked from the 7.5 inch barrel at a distance of twelve feet" in a 50oz gun! That hurts my hand just reading about it! I've shot the Maximums off the bench but those numbers are off MY chart for fun and games. The FA has a smaller chamber pattern, but in a 5 shot 500 it gives a thicker cylinder wall to chamber wall ratio. That difference changes at a rate of 2:1 with different chamberings. Thanks for the info jeffquinn

It felt like that revolver had a thirty-pound trigger pull. My brain was telling my finger to pull the trigger, but the finger just did not want to do it.
I much prefer that bullet atop ten grains of Trail Boss., instead of a pint of Lil'Gun.

I incorrectly used the term "bulged" earlier If the cylinder hit the top strap and left a mark, the chamber was buldged. The top strap just kept it from buldging more. You used the term correctly.
