I'm 5' 11" and 200 lbs.
In no beast by any means, but I can handle it; I don't care to shoot a box of them at a time, but if that means you brought enough gun, so be it.
You'll be ill prepared if you face a moose or Grizzly with a .270; and I'm a .270 nut.
Same here. I'm a .270 nut also and I would want a bigger caliber for Alaska. Even if he's not hunting bear or moose they are still around. The .270 can kill any animal up there but imagine being up there in reality and being faced with a 2000 pound Grizzly. I would want a bazooka.
