Which load is harder on a gun, accelerates wear, reduces the service life of a weapon more?
A 124/9 at 1120 fps but at +P pressure (EFMJ), or a 124/9 at 1150 fps but at std pressure (Gold Dot)?
Too close to call?
What's harder on the gun, the higher pressure or the higher velocity? How and why?
If two loads have the same power factor, say a std pressure 147 at 995 fps and a +P 124 at 1180 fps, why is the higher pressure load harder on the gun (if it is)?
What has more effect, if any, on how hard the gun unlocks, how fast/hard the slide hits the frame, etc, the pressure or the velocity of the exiting bullet? If pressure doesn't effect any of that, how does it stress the gun?
If two loads of the same weight have the same velocity, but different pressures, do they have the same impulse, recoil velocity, recoil energy, etc?
Just wondering how those interact.
Probably didn't ask it very clearly, hoping ya can figure out what I'm getting at?
