I don't own an AR-15, but I hunt coyotes and pigs with my Mini-14.
Also, a really good friend of mine who has been my hunting partner more times than not hunts the aforementioned coyotes and pigs with his AR-15.

Trooper pal: "Says the guy who thinks .38 Super and 10mm are viable pistol calibers and gets mad when Wal-Mart doesn't have them."
