A customer of mine hunts foxes during the season. Last season he had me take pics of where the bullets went in then exited. I obliged after skinning them ( he gave me the foxes). He has been worried to death that his .222 will tear them up again like he had a problem with the year before. I think he said he shot a groundhog with the same gun and he couldn't find an exit, but he was using vmax rounds then I think. He switched to a different bullet type and the foxes have been mostly ok. Vmax will frag up, but the foxes were being ripped up. But a .308 is much more powerful than a .222. He uses .222 as he doesn't trust stuff like .17hmr for coyotes. BTW I was considering shooting a mangy fox with a .50 cal muzzleloader, but it was still early for deer to come in and I wanted a deer.
