there's simply no comparison in the effect of a 230 gr bullet at 800 fps and an 80 gr bullet at 2300 fps. Same diameter, same recoil, same momentum, but the lighter, faster bullet has nearly 3x the energy, and man, does that difference ever show in the effect on the flesh and blood target. That is, if the bullet is designed and made to maximize the use of that energy. :-) Since the 230 gr .45 overpenetrates and wastes about 1/3rd of its 350 ft lbs of energy, and my design uses all of its 930 ft lbs, it's really got 4x the energy to work with.
You don't need lots of penetration on men. That's why bullets designed for use on coyotes and small deer work so well against men. You don't want or need an exit wound or blood trail on men, the way you do on deer. You don't shoot men from the ass-end, the way so many jerks want to be able to shoot deer.
