I'm pretty sure Carlos Hathcock preferred match ammo for hunting commies in Nam, and would use M2 ball out of his Winchester 70 30-06 if that wasn't at hand in the field. You might reasonably argue that a larger game animal could be harder to kill, except with a competently placed shot that point probably becomes moot as demonstrated here. Even though I think the marketing machines called ammo manufacturers have done too good of a job in getting us to believe all they claim, I do use "hunting" ammo on large game just the same. On the other hand, coyotes get the cheapest M80 ball I can feed them and they work well in dispatching the pests. As long as it's a free country, just follow the law and do what works for you in your own experience.
