Does anybody really know the answer to this? I mean, I could go on about the wonders of Hydrashock or Golden Sabres, and others can talk about different brands. But do we really know what the hell we are talking about? To me, I have gotten a bit cynical about the whole thing. I'm thinking that if its a jacketed hollow point that feeds reliably and goes bang every time, I'm not sure that there is much of a difference. Am I wrong here?
FQ13 who doesn't want to be carry trash, but I'm not really sure how one quality brand is that much better than the other as long as your pistol likes it. 
I agree with Quaker to a point here. That point is really "knowing" what and how a bullet will perform when coming in contact with the target. I know there's the ballistic gelatin test created by Dr. Martin Fackler but even he'll tell you it is an
approximation of what happens when a bullet penetrates a human. So I guess I'm saying nothing is 100%.
I use the Winchester 147 gr PDX1 rounds in my 9mm and as far as velocity they are traveling about 950 fps +/-. I would say to MaOfficer to try several different brands and test them using this procedure:
From low ready/high ready with your support hand only.
Fire 6 rounds into an 8" circle at 10 yards in 3 seconds.
The purpose for me is to see if I can control the gun with this round with my support hand to see if I can get "combat accurate" hits on a target in a short period of time. If the gun is snapping so badly that you can not keep the rounds on target, try another.
Disclaimer: I am definitely not an expert on this so I know there is much to be improved on with my approach; but there is some logic to it.
