it’s a long thread with a lot of pictures, but consensus seems to be 450 or so is the limit. If loaded hotter (223 AI, 22 creed, 22-250, etc) you could extend that, but close range performance would suffer.
People will poo-poo hunting with a .223, but it absolutely works. Same for the 6s, 108 ELD-Ms have taken tons of game. Hell, the 243 Win has been killing for 70 years with lesser bullets.
Not apples to apples, but the outfitter recommended against me my 6.5 CM on my recent aoudad hunt, saying “I’ve lost more than I’ve recovered with the creedmoor.” I didn’t even bother telling him I was using match bullets, not worth the hassle. My ram dropped within a couple feet of where I hit it.
