.223 on whitetail

yeah i’m looking to build out a 6.5 grendal sometime in the near future as a dedicated deer rifle and .223 is definitely not my first choice (been hunting with a .308 myself) but some people seem to have good success with it while others seem to view it as taboo. i guess it would come down to good shot placement and proper bullet selection. i killed a couple of does a few years back with 7.62x39 and was just wondering how .223 would stack up. picked up some Hornaday Superformance tipped with the gmx, and if i decide to give it a go that’s what i’ll be using. ps: it is legal in both ga and sc and those are the two states i hunt.
