I just shot a bison in Montana with 338LM. 265 ablr, 2840 FPS at sea level. Shot was exactly 200y broadside into the ribs. Broke 2 ribs, bison staggered, went down, but got up. Stood around for a bit and walked off. Tracked it about a mile before my dad finished it with a second shot from .280 AI, From what I can tell the 265 barely made it into one lung, I expect it mostly just blew up after hitting the ribs.
