Max pounds force of revolver cylinder against frame?

[Chris Sweeney]

Just looked through my Lyman Black Powder handbook:Load data for 44 revolver (which starts at 19 gr. and goes up to 37!) pressure is listed in the 5000 LUP range. It lists the Italian National PROOF load as giving 10,677 psi. Of course that's with Curtiss and Harvey powder, so YMMV.

Just as a reference, looking through some of my reloading manuals, a 200 grain 44/40 @ 1100 fps with smokeless powder, generates 12500 psi. Factory 230 grain 45 ACP loads range from 17000 to 19500 psi.

I think we are trying to correlate pressure, force, energy, work, and time into some "ouch" factor. If the weather ever clears up so we can shoot, we'd stop thinking all these dangerous thoughts

Say it was 10,000 psi. That would be 1590 lbf that the cylinder put on the frame, but that's only if the frame were mounted rigidly to something big hard and heavy and did not move backward due to recoil. Conservation of Momentum would come into play. Mass x Velocity of the ball would equal Mass x Velocity of the gun, but only if the gun were floating freely in space. With it held in your hand, there is also the added mass of your hand and arm and whatever else is moving backward and none of that is inelastic so the computations get complicated.
