I've had more deer drop at the shot with s 223AI than anything else I have used to date, and I've used a bunch.
Drilling shoulders and 200 pound deer don't scare me in the least, if they do others then so be it. There is nothing inhumane or 'iffy' about taking one into the deer woods, that's for damn sure.
No doubt the 243 is good and trumps the 223 at longer distances, but not by a crazy about. 75Amax needs and extra 3MOA dialed in to hit at 1K then a 243 shooting 105gr Amax. House that same 75 in a 22/250 and the 243 comes up short.
