Ole Flyer knows his stuff! I conseede on the Beretta. Never fired one, only looked it over, so really can't say. But the short barrel length does concern me as far as hollowpoint expansion goes. We didn't get too gooda results with the P32 a few years ago with JHP's in the wetpack test so a shorter barrel isn't gonna help. And remember Goldenloki's data kinda said the same thing with gelatin. http://www.goldenloki.com/ammo/gel/32acp/gel32acp.htm
But maybe CorBon's hot stuff (I hate it) might still expand in the Beretta since it did pretty good in the P32, as I remember.
But then, I think we all agreed a long time ago that FMJ's were the best way to go in .32cal short barrels, like the P32, anyway.
Here is one of the finest web pages anywhere on .32acp JHP expansion......
He has a excellent table down the page for the P32 with factory loadings. Best I've ever seen.
Later, when I get time, I'm going to try and duplicate Ricciardelli's water jug test with the P32 and Win Silvertip ammo. His tests were all with the longer barrel Walther so it'll be interesting to see what happens with a P32. Only drawback is the jugs are only good for one shot. Hard to draw a statistic with only one data point! We'll see.
In the meantime, thanks, Flyer, for all you do.
