What's your motive, bear defense or hunting? The 7.62x39 is usually compared to a 30-30, but slightly smaller in the hole-punching department. Lots of people will agree that it is sufficient to kill a bear with a well-placed shot, but sufficient usually isn't best to bet on in terms of defense...or hunting for that matter. I've only ever handled one Norinco SKS, and my humble opinion is that this particular rifle isn't sufficiently accurate or reliable. Didn't jam often, but often enough to rather not potentially just piss off a bear with only a bayonet.
Lot of folks who swear by their SKS's, but that's just my experience...
Rumor has it that Canadian Rangers up north are still issed No4Mk1 Lee Enfields for bears because they're of the few guns that don't muck up when half frozen...has anybody else heard this? Respectable sporters usually go cheaper than SKS's...
Couch-Gator: Good deal, them 820's. Out of stark coincidence, I'll be doing some prospecting myself in the mountains north of Vancouver...though probably a bit further east.
