Im taking a 6.5-06 to BC for my Moose hunt. Shooting 127 gr Barnes LRX at about 3000 fps. Your .300 will get the job done. Good Luck on your Hunt.
7Mato, good to see you feeling better are heading north this fall. Hope all goes well and you bag a big one with your 6 & a half-hot six. Those Barnes should let the air out of one, for sure.
I'm heading to Alberta for moose in early October, but I'll be taking my 35-06...of course
along with some 225gr TBBC's.
