My .45 carry ammo is a 165gr HP Winchester Silvertip which is not +P or in 9mm it is a 115gr HP Hornady Critical Defense. The perfect self defense or military ammo would be one that penetrated about 6" with a permanent 6" wound channel.
Well, yes & no. You are using a 185grWSTHP & the perfect round would NOT make 6" deep wound. A large man's forearm can be almost 4-5" across. hit that in front of his chest & you will disable the arm but not get near vitals. A large, heavy man will have 3-4" of fat & muscle on his chest, hit that & you will not hit vitals, we won't even discuss oblique or 90deg angle shots into the torso. It's why the FBI came up w/ the 12" min. penetration. It allows you to get to vitals from any reasonable angle.
So the perfect round would penetrate 100% from any angle then drop to the ground. Those do not exist.
High velocity handgun rounds, say, 1100 fps+, should create more BPW than rounds in the 950-fps range. I think that we give weight too much consideration and not enough consideration
There isn't much diff in temp cav form 950fps-1100fps. You have to get the vel. up, well over 1200fps to see significant diff. Again, bullet design has a lot to do with that. So in the end, I don't think rifle shooters look for anything really diff. It's just as vel goes up, bullet design is even more important to sustain vel. Vel. alone will not kill. Roy Weatherby tried selling that in the 1950s. It helps a properly designed bullet do more work, but there is no magic to HV impacts at what we would term normal vel. of 1200fps-3000fps. The bullet still has to do the work.
"Given adequate penetration, a larger diameter bullet will have an edge in wounding effectiveness. It will damage a blood vessel the smaller projectile barely misses. The larger permanent cavity may lead to faster blood loss. Although such an edge clearly exists, its significance cannot be quantified".
