We are trying to get a project togeather to re-release Wood Bison in the Yukon Flats, and several other areas of the state. The biologist tell us that the Wood Bison has no natural enimies or preditors due to it's size. They are too big for anything in Alaska to mess with. Yes a Grizzly could easily kill a calf, but they have to get around Mama first. That's not likely to happen. The Wood Bison is much larger than the Plains Bison that everyone is used to seeing.
Here in Alaska we have free ranging Plains Bison, (Buffalo) The state has minimum ballistics that can be used for hunting Buffalo. The .308 Win does not qualify, 30-06 just bearly. Saw a fellow try and take a small Moose last year with his Whitetail gun, a Remington in .308 Win. It took seven shots for him to drop the Moose, and this was a small one. He claims to be a great Whitetail hunter that kills five or six Whitetail a year by hunting in Verginia, Maryland, and North Carolina. Yet the Collins twins use a .308 every year to take their Moose. The differance is that Jullie and Micky Collins know how to get close and place the shot. Sometimes the Moose drops on the spot, other times they just sit back and quitely wait for the big fellow to drop, with out spooking him out of the territory.
If hunting in the lower 48 states, the .308 is adiquate for everything. In my openion a little light for Elk, but adiquate. For Alaska leave it home! Yes it can easily kill Caribou, Black Bear, Musk-Ox, and Black Tail Deer. But it is too light for Moose, or Grizzlies. And deffinately not adiquate for Brown Bears. Forget about Bison.
