RE: .243 for whitetail
25 years shooting the .243, and at least 50 deer with it, and only one made it past 50 yds. Big hogs with complete pass throughs at 200+ yds.
It's my go to rifle. I prefer hornady factory ammo but the federal comes in a close 2'nd. Dont know what else to say, it's a little devestating on the meat though, the only other gun that I have seen leave this kind of destruction is the 7 mag.
