i've never hunted deer with a .223 rifle. That's because i use a muzzleloader for deer hunting. However, many wild hogs have fallen to my .223/5.56mm rifles. The 55 grain Sierra Game King does a good job on big hogs, ditto for the 53 grain Barnes TSX.
BTW: In Oklahoma it's legal to use the .223 on elk. A couple i know owns a place over run with elk. Every year the wife kills a big elk with a .223.
