I would nix the SKS, or any semi for that matter, for a newbie or kid hunting rifle. It's far easier to make safe a bolt, pump, or lever after loading the chamber. With the SKS you might let the bolt fly only to not get the shot you want and have to hike after the deer. This leaves the newb with the difficult proposition of making the SKS safe. You have to drop the bottom out and catch your expensive (comparitively) hunting rounds, throw em in your pocket, and then rip the bolt back to get the chambered round out (which invariably slips out of your hand and lands in the snow).
Traipsing around the bush might involve having to "make safe" your rifle multiple times. While you or I may be comfortable slapping the safety on, I'm not comfortable having with the greenhorn behind me doing the same thing.
With a bolt-action, just crack it open and I'm satisfied. Takes a half second and is easy to remember for someone new.
