Wally has a good point, the 180gr Core-lokt has probably killed more elk than all the rest of the bullets combined, forever!! My first elk was killed with one out of an A3-O3, then I killed a few with em in a Rem 760, they aren't the best bullets for penetration, but all those elk sure didn't know it, and neither did I!! Most of the recovered bullets were found just under the hide on the off side, usually in pieces, but they had done their job resulting in meat to pack!!
FWIW, I've only recovered one Failsafe in the spine of a bedded cow, all the rest were clean exits, just behind the shoulder, save the meat!!
