RE: Elk Gun?
From all reports I have received, the Fusion ammo is great. I'm hoping they come out with the bullet as a component sometime soon.
Also, if you really aren't recoil sensitive - get the .300 Winchester. Most folks on this board, if the truth be known, use lighter calibers because they kick less. The .300 Winchester will give you a little more margin for error if shot placement is less than ideal.
