No problems killing anything, just don't like the bullets. I used them on deer, can't say I was impressed with either of them. Shooting thru both shoulders on elk from 300+ yards and exiting tells me the NF didn't lose enough velocity to matter. And that was from a 30/06. From a 300Wby they've done it from 400yds. You should try some of these under actual hunting situations, you might like them😉
