My own family members have killed grizzly bear and moose with 308s, where you hit them. One of the Indians down ft Yukon killed a sow polar bear with a 556 bout 15 years back.
Put a MS2 sling on them and everybody hunts off snowmachine; subsistence of course.
I paid $106 for mine. It came with a thing you wore like big suspenders that had a bunch of cartridge pockets in it. My dad got one too for the same price. His also came with a bayonet. I inherited his last summer. And another thousand rounds.
