If you shoot enough bullet at enough game you'll likely have something go wrong some day, if you don't recover the animal a guy just don't know 100% what went wrong. I've nearly lost a couple elk shooting Barnes, the bullets failing to penetrate into the chest sucked but I figure it was partially my fault for putting them on the shoulder bone and giving them a chance to deflect, had I held 6in back I would still be shooting them by the truck load and never started shooting Bergers.
I'm glad I had a little hiccup and discovered one of the best hunting bullets I've put on elk, Bergers!!!! Also nice to have very consistent sub MOA groups a long ways out there and not having to do any copper mining
I do still like the Barnes for certain applications just not for long range hunting, actually starting a build wrapped around a Barnes, do like the looks of the Cutting Edge bullets for an all copper but they are also made to open dramatically according to the literature, they may be nice.
