OK so like all these tests they are skewed a bit. I think some, not by intention, but by the nature of the beast. Take the depth of penetration. Unless the shot is taken at a side profile or shooting from above/below why do we need 15" of penetration. 10" would be more than enough even from side on. So anything that would open up a bit faster and, or wider would be a good thing.

Then there is controllability so you can be back on target for subsequent shots.

The author has laid down the goal posts well. That is he is talking about non central nervous system hits. As we know a heart shot can be drop to the shot or keep going for upto 30seconds if on drugs about 10 to 15 if not.

Yes my ranting has a lot of holes in it. However I find the article very good. It shows, to me, what should be the more effective stoppers with modern semi auto pistol ammo.
