There have been a lot of elk killed with the 180 Gamekings out of a .300 Win Mag. Just try to be careful on close range shots. And avoid shoulder shots. Broadside in the ribs at 400 yards, you will think they are great.

The 180 Hornady Interlock has a pretty good reputation as an elk bullet. I personally use the Sift Scirocco's and can't say enough good things about them. The Nosler Accubond and the Tropy Bonded Bear Claw bullets are also very good - as are the 180 gr. Speer Grand Slams.
