Depends on caliber and velocity I guess. I've shot quite a lot of deer-sized PG game with calibers larger than normally required, at way less than warp speed with both solids and TSXs. The combination actually does quite well and is very predictable. Usually complete penetration and always less than explosive expansion. A white-tailed deer could be considered equivalent to an impala I guess and those calibers and bullets like the TSX kill them very nicely without excessive meat damage. Now feral pigs are something a little different. Smallish ones, while very "dense" type animals as most porcine are, are still small. So really no different from something like a deer. But the occasional big one, the 400+/- pound variety, is big and dense by any definition, so a larger caliber with tough, DG bullet, would not be considered over gunning at all. The bigger mistake of caliber and bullet would be going the the other way, as many seem to do with current trends. High velocity- smaller bullet.... huge mistake for pigs, especially if the occasional big one shows up!
