The 300 mags are outstanding rounds for hunting here in the states.........as well as around the world. I own a Ruger M77 MArk II in 300 win mag & a Weatherby Mark V in 300 WBY. Both shoot factory ammo into 1 MOA. I have used the win mag to take several long range deer. It dropped them in their tracks at over 300 yards. I have taken it elk hunting but did not get a shot. I have yet to use the WBY on game. But if I ever go after elk with a rifle again instead of my bow...the WBY will come along. And it may also go with me on a winter caribou hunt in Canada.
