Most guides will carry at the least the .338 if they are around brownies in Alaska, the black bear though can be dropped with something much smaller. My mini 14 was sold to me by a guide that used it only for the black bears.
And for those Kodiak grizzlies give me air support! Either that or an autoload 20 or 25mm.
My old man was seriously injured in the wilderness when I was a kid. He said afterwards, and I took it to heart, maybe to extremes, never go into the wilderness alone. It almost cost him his life and did cost him a leg.
I'd love to go see Alaska. Have wanted to since I was a kid. But I'd definitely want to have a hunting buddy with me!
