I love that tired old "the average black bear is only about 5 pounds..." crap that always comes up on these threads. Yep, we all yearn to shoot an "average" animal, and will happily pass up an exceptional one. For sure, the only rifle worth shooting is the bare minimum that will work...
I have an SKS, and I enjoy shooting it...but can anyone deny that it's just about the crappiest hunting rifle in the world? If the SKS had never existed, and someone designed it today, then built it and attempted to market it to the public for use as a hunting rifle, they would be laughed clean off the planet. If that's all a person can afford, the Mosin is also available in that price bracket and would make an infinitely superior gun for hunting bear or anything else.

My biggest complaint with the SKS for hunting (and I've actually used it successfully to take a deer - last fall, kinda to prove a point to a friend who kept ragging on the SKS), is that it's a heavy brick to haul around through the bush.
But for the price point (and really, when we're talking SKS, it's all about the price point), it's a good all around gun that you can hunt the smaller ungulates with. As an all around truck gun/ranch rifle/rough rugged and ready do-all, I'd take an SKS over a Mini-30 all day, every day, even if they were the same price.
There's some serious snobbery when it comes to any gun discussion. To me, it's all about "can it get the job done" and the SKS can get a lot of different jobs done. Are there better choices for any individual job? Absolutely. But so what? Run the gun you brung.
One of the best things about an SKS for new shooters and hunters, or even experienced shooters and hunters who happen to be on a budget, is you can get the gun and a couple thousand rounds for less than you would pay for just the gun for most hunting rifles. This lets you take it to the range and the bush and shoot and shoot and shoot until you know it like the back of your hand and it becomes an extension of you. That level of familiarity with a so-so rifle will trump the high budget hunter with a $2k Tika that gets sighted in once at the range, which counts as the only practice the Rolls Royce hunter puts in all year.
