I shot the 190gr Bergers in my 300wsm, for deer and antelope they work great, just as advertised.
I've only shot one elk with them and I wasn't impressed. It was a bull at 724yds, first shot behind the shoulder and it hit one lung and exited out the bottom of his chest with very little expansion, he just stood there bleeding so I put one more on the high shoulder and he dropped like a ton of bricks. It took and hour to ride my horse with a pack string to where he was laying. When I walked up to him he was very much alive and needed a finishing shot. The second shot blew up on the shoulder blade and never penetrated past the blade.
This was only 2 shots on elk but both bullets did not perform as I would of liked and I wasnt willing to risk it again. I now shoot 180 Accubonds for elk and patiently waiting for the 190gr LR's to start shipping.
