I've shot deer with my own 50 bmg. I don't know where all this huge hole stuff comes from. Mine have been 50 in 50 out, and run like hell too, leaving not much to trail. Trailing the path of the slug in the brush was easier than the deer for sure.
YMMV I guess.
Shockwave... ROTFLMAO
Saw a guy shot in the arm a few inches from the wrist with a .50 cal. .50 in, .50 out, and no real damage. Luck and a hell of a scar.
