Probably 95% of the hogs I shoot fall to my .223. The more I use it, the less I am willing to call it marginal, especially with Sierra Gamekings. Every hog I've shot with it has dropped quickly, most in their tracks. I shoot it accurately, and can get off accurate shots with it quickly because I shoot it all the time, so that's what I use. Dead is dead, and .223 dead is just as dead as .308 dead.
