I haven't bagged anything with the ace, but my consostancy was terrible with them, I switched to woodsman, and they're grouping alot better, but they're also needleoint... as far as the penetration, alot of people prefer rounded off tips specificly fer that reason, but itd hard to say.imagine a deer was looking right at you, his butt end behind his head, like a quatering stance, barely showing any vitals. my dad had that shot, and with a 70 pound bow he only got 6 inches of penetration (with a coumpound expandable broadhead!) good luck man, -jimmy
