",,, recovered from buffalo, which are the so far only thing I've found that would stop them."
70 guy: I have a 400 grain 416 bullet that I recovered from a zebra. The front of the bullet expanded to 3/4" and the rest of the bullet looks like a solid that could be fired again. It was shot from a 416 Ruger at 2400 fps. Broadside shot that I expected full penetration and exit.
