I'm looking for a lever action bear defense gun for backpacking in grizzly country (Alaska, wyoming, etc). I think i've narrowed it down to the marlin or w 94 in .444. However it seems winchester dropped the Big Bore model from their catalog. I was wondering if maybe the 94 can't handle the .444 because I hear good things about the other calibres. Any input? The marlin guys are getting pretty convincing! Thanks.
