Preacherman, thanks for re-emphasizing the data from firearmstactcial. The information is very enlightening and that is why it got posted early in the thread.
clubsoda22, the idea that somehow a lawyer will work the high performance bullet against you is unjustified for justified shooting. If you have a negligent discharge, then the round's supposed amazing performance might be used in conjunction with your negligence. Similarly, if you shoot somebody for a reason that is not self defense, the same issues may come up.
Nobody has managed to produce a criminal case where a shooting was ruled as justified but a decision went against the shooter because he used a mean sounding named gun, mega-lethal ammo, too big of a caliber for the situation, etc. If you are justified to use deadly force, whether you use a .25 acp or .50 BMG is not the issue. Both carry they same criminal/legal ramifications.
Of course in civil court, anything can happen. Hollowpoints are supposedly to cause the most pain and damage. Ball ammo can be called "bone crushing" ammo. No matter what you use, some trait can be pointed out about the ammo and made to seem horrific. Don't sweat it.
If the claims of Aguila are true, then maybe it could be billed as really safe since it doesn't penetrate dry wall so well?
