Dirt and crud in your firing pin hole in the bolt. Cure: keep it clean and dry. Clean regularly...
Slamfires are a problem common to many first generation SA rifles. Meticulous cleaning helps, but does not address the root cause, which is improper (by modern standards) firing mechanism design.
The 49 FN is another rifle prone to this problem. In ythe 70's, when these rifles were more common, the answer was to fit a 2 piece firing pin. The theory was that the inertial force would be reduced. Titanium firing pinsa were also tried.
The Tokarev rifles are also bad actors (I personally had one rip off a 3 round burst).
Any fix for these old arms will be a bit of a lash-up, so, although I hate to say it, "Ya gets what ya pays for".

I think pretty much all the most likely problems have been mentioned already. My advice would be to make sure the bolt and firing pin are super clean and dry. I spray it out with brake cleaner. That removes all the grease/oil/cosmo. Do not oil the firing pin. It should rattle in the bolt.

Every time you want to take your SKS to the range, perform this simple check:
1: Place hand over mag cover to prevent it from rattling.
2: While still holding mag cover, hold the action close to your ear.
3: Tilt rifle back and forth and listen for the firing pin falling freely back and forth.
If you can hear it sliding back and forth, you won't have a slam fire unless you use light primers meant for bolt actions in your reloads. If you use proper CCI #34 milspec primers, or milsurp ammo, you will have zero problems.
