Most of my life I've hunted primarily with 7 mags with a few .270 kills, usually with bullets like Interlock, hotcor, fusion, etc. I wouldn't bet any money I could look at someone's deer exit hole and say which caliber caused it. Recently I've gotten into.308 and 30-06 and It seems to be more blood from the entries.
I'm remembering a .270 with a norma factory 150 gr. hit a mule deer standing broadside on a steep hill. It blew about 3"or 4" dia. hole thru the exit and a bunch of bone and lung tissue onto the grassy hillside. That would seem to have been a much bigger gun to cause that.
