. Good points. I mentioned earlier it’s a 20,000 psi ACP vs. 15,000 psi Long, .3125 vs. .312 and then a jacketed bullet which should increase pressure over lead. .32 ACP won’t be seeing the inside of my S&W Model 1903 anytime I can say that for sure. Would not hesitate in my .32 H&R though. I guess the way to put it to a real test is to shoot the ACP In a test barrel. Don’t really have a need though. Other than to be able to go bang in an emergency don’t really see the point.
