Depth and breadth
The SKS is a fine "survival" rifle, if that's why I'm in these supposed woods.
If I'm "lost" in the woods, then I want a combo rifle in .22/12 gauge. The 12 has a wide variety of loads, and if I'm hoping to be found, I can carry some of those flare shells found in most sporting goods stores. Also, 12 ga is a good noisemaker, which helps searchers too. The .22 is good for small game, and a cartridge can be broken open for use as a firestarter; also, carrying 200 rds is easy.
.223 is also acceptable in place of the .22, and better in fact in some ways, but the most important part is to have a small caliber round that is lightweight and easily carried. Both .223 and .22 are available in tracer rounds, which can be fired to draw a searcher's attention to you.
For a handgun, I want my Model 66 with 180 or 200 gr hunting loads; manstopper, yes, but will be my last defense against a bear, too, after I've fired the shotgun.
