I suggest you take care of the basics first, before introducing different variables like an aftermarket stock, is the trigger horrible like a gate latch? If so, you might want to get an experienced gunsmith to give it a trigger job. Also try Privi Partisan 123 grain soft point, In my opinion, the CZ surplus ammo shoots way better in a Cz-858 type rifle than in an SKS, and my sks always shot better with Privi Partisan. You might want to experiment with bedding, for that you have to do some experimentation. Have fun be safe. It seems like everyone's got an opinion on how accurate sks's can be yadda yadda yadda blah blah blah.
