What do you look for when looking for penetration? Talking .45 acp. I have found the .45 acp +p looks like it has more power than those rounds that are not +p, but I'm guessing. I have a P90 and want to know what rounds will give the best penetration/killing power.....talking animals here, no I'm not hunting them, just going to be in their area for a while.
I have also noticed, some have different lengths that others, like 1.19", 1.210", 1.200", etc..... is that due to the length of the bullet?
