I was only talking about hand gun ballistics.. I really never had an interest in 9mm 16" rifles.. I guess the +P+ ammo was designed for rifles right? Anyway I was looking at a bunch of slow motion Gel tests on all kinds of ammo on youtube and you can really see the difference in shock from .380 to 9mm to 357 to 44 -223-30/06 all the way to .50bmg... some of the new 9mm is quite respectable.. look for the slow motion ones
Heres the 45acp hard ball I think
and 45acp SD
357mag
and 9mm
