A couple seasons ago I hunted mainly with a T3 SL in 223. Shot 75gr Hornady HPBT into little groups and did the job on the only buck I shot that season. About 120yds buck didn’t make it 15yds and collapsed. Only complaint was no blood trail but one wasn’t needed.

Our deer are easy enough to kill, I could do my hunting with a 223 if needed/wanted.
