outerlimits Posted August 10, 2006 Share Posted August 10, 2006 Do the test with a 38 super and a 45 both loaded to 170-175 PF. Use a video camera and a background grid to record the angular velocity of the popper as it falls. I've got money on which one drives a popper down faster. i remember using the pendulum to measure power factor. then, around about 1988 or so, we were into 38 supers using 162 gr bullets to get major. i used to shoot pins too so i remember trying to do it with my super...the pins just laughed, some rolled over, but shooting them with my 45 pin gun, they launched off the table...no comparison with the same hit factor, but other variables involved-mainly mass of the bullet.

boo radley Posted August 10, 2006 Share Posted August 10, 2006 Put a timer at the base of the popper. I'd think it would be able to record the sound of the bullet hitting the steel, then the sound when popper falls.... Link to comment Share on other sites More sharing options...

vluc Posted August 13, 2006 Author Share Posted August 13, 2006 LOL! You guys are right...too much free time on those drives to and from work!! Thanks for all the responses. No dog in the fight, just curious! Link to comment Share on other sites More sharing options...
coltgov Posted August 28, 2006 Share Posted August 28, 2006 (edited) If a lower mass higher velocity bullet totally fragments when it hits steel, it will impart less energy than a much heavier slower velocity bullet that stays more intact hitting. Both are at the same PF. This is what I observed shooting metalic silhouette with a high power rifle. Edited August 28, 2006 by coltgov Link to comment Share on other sites More sharing options...
Flexmoney Posted August 28, 2006 Share Posted August 28, 2006 Yep, it not only about energy...it is also about transferring that energy to do work. (Come on...somebody talk about "dwell time"... ) Link to comment Share on other sites More sharing options...
tightloop Posted August 28, 2006 Share Posted August 28, 2006 The British are big on the dwell theory...need someone to comment with the appropriate amount of esoteric BS...... I'm with Benny...just shoot the damn thing. Link to comment Share on other sites More sharing options...
