Quoted:
Maybe you should reread what I said. I said that in a short barrelled handgun there is a limit to how much velocity you can obtain. This is not controlled by chamber preasue but by the lack of the ability to burn powder in a short barrel. READ a few loading manuals, you will see that even in a 6" barrel the 38 spl with a 110 gr. bullet is limited to about 1100fps. In a 2" barrel you will be lucky to get 900 fps, I know this because I've tested on a chronograph many similar loads. Also my loads for the 38 spl's that I've tested DO NOT EXCEED any loading standards which I have studied, and I have studied everything there is to study about loading small arms ammo. .
Ok, I reread it and your original assumption is still incorrect. Your assumption in the above post is even more incorrect.
And I've been reloading for close to 40 years, I've read more reloading manuals than you've got digits.
The limit is chamber pressure, not powder capacity or barrel length. Yes, barrel length and powder capacity may play a factor in limiting velocity, but only because we can't use faster powders to give a complete burn in a shorter barrel, the pressure spikes too high. Why do you think powders come in vastly different burn rates?
I can drive a 230 grain bullet out of a 45 ACP at 2000 fps with a super fast burning powder and it will completly burn....as long as I'm willing to blow the gun up. Again, pressure is the limiting factor here, not barrel length.
And your info for 38 Special doesn't cover +P loads. I can safely surpass 1200 fps with +P loads and a 110 grain bullet in a 6" barreled revolver. Assuming of course that it's safe to fire +P loads in it. Again, chamber pressure, not barrel length is the main factor here. With a nearly identical revolver chambered in .357 Magnum, instead of 38 Special, I can push that velocity to 1500 fps. Same barrel length, same bullet. Explain how this fits in with your barrel length being the limiting factor theory?
Yes, shorter barrels will cost anywhere from 50-75 fps for each inch shorter (of course there's a point where a longer barrel will also slow the bullet down, but that's a topic for another time). But if pressure was no factor, we could simply keep using a faster and faster burning powder to make up for the shorter barrel length. But when we do that guess what happens? Pressure spikes beyond what the gun can handle. Why do you think we can load a 45 LC in a Ruger revolver to so much a higher FPS than for an original Colt SAA with identical length barrels? Because the Ruger can handle more pressure. Once again, pressure is the main limiting factor.
Your premise is incorrect, and dangerously so. Take your own advice, read a few loading manuals. Specially the part with the words PRESSURE and DANGER in red letters.
Edited for spelling.
