Hunting bullet performance - prefer through or a grenade inside?

[35WhelenAI]

195 yds. I’ve killed a bunch of deer and a few antelope with that bullet and get an exit about half the time on deer. It’s super accurate out of my rifle.

For what it's worth, I get exits on anything but hard quartering shots out to 355 yards with the TTSX from the Whelen AI (.358 200 TTSX) on elk and more than adequate destruction of the vitals to cause certain death. 270 Win and 30-06 shooting a 110 TTSX and 130 TTSX respectively exit on deer sized animals out to 400 yds. Never shot at an animal beyond 400 yds, so no experience past that.
