Re: 300 RUM - Nosler or Sierra Gameking
I started using the 300 ultra mag this year and I am really happy with it. I killed a Dall Sheep in Alaska at 576 yds and a Whitetail in PA at 703 yds. I use 100gr of Retumbo 180 gr Nosler BT, Fed 215m primers, OAL 3.600. This load in my rifle is just shy of 3500fps., 26"HART barrel.
