As mentioned above bullet weight, construction, and velocity has more to do with exit holes than diameter.
heavy for caliber bullets are often pass throughs on a heart, lung shot. I was given a 26 inch custom 270 win when I was about 14 and maybe 98 pounds. I was into reloading with guidance. little 100 grain were devastating varmint rounds. as to deer rounds 120 - 130 make massive exit wounds and the deer are DRT. 150 -175 grain with great BC seem to leave small exits at long ranges and the deer often doesn't move 50 feet. Never had an exit on Bison and both DRT heart shots.
I like cals that are very available and cheaper to shoot. I sold all of my cannons like 30-378, 338 Lapua, 416 rem, 458 win mag. Those are all bragging rights rifles
I have made 1000's of 260 rem from 308 range cases. That is a wonderful round for white tails and smaller game. I also have a 26 inch 257AI roberts that is a wonderful mule deer getter. I'm a 270 win man. or even 270AI. cheaper to shoot than the 270 wsm
