Using cold or heat is not " a magic recipe" to free or assemble parts. Standard procedure in assembling machinery. When I use to build Die-Cast machines, we dipped brass bushings in liquid nitrogen. They would slide right into the bores of the platens and then lock right up when they warmed up. Heat makes things big and cold makes them smaller. Water is the only thing that gets bigger when froze. Good example is phone lines, sag in the summer and tighten up in the winter.
SKS Doubled! Was it the ammo, the rifle, or me?

That is pretty cool. Maybe I will give it a try after all. In the meantime, I got my hands on a set of punches and got the bolt apart. It wasn't terrible in there. A little bit of oil and residue. Overall it was in superb condition. I gave it a cleaning with cotton swaps and some solvent. I attended to all the channels and nooks before reassembling the bolt and slapping the rifle back together.
I so enjoy the SKS for this very reason. Nothing scary in there. No match tolerances or complex designs that require a call to customer service. It is so easy to maintain. I feel like if anything ever breaks then it won't be a huge mess to learn how to replace the part myself. I like the idea of being my own armorer. And the SKS is just that type of firearm designed in part with that in mind.

You need a vice and a strip of leather or something think to protect the bolt. Wrap the material around the bolt but not blocking access to the retaining pin. Lock it into the vice and use a steel drift pin and hammer. It'll come out. It would be better done with the vice and an arbor press but those are somewhat pricey.

I never got my bolt apart, but I soaked it in mineral spirits and that dissolved all the cosmoline out. It moved freely after that.
On doubling, I have doubled with my M1 Garand, my M1A, and my Vepr. It was due to shooting off a bench rest with a rear support and not keeping the rifle firmly against my shoulder. The recoil and the gradual trigger pull causes it similar to bump firing. I have pretty much sworn off using a rear support for my semi-autos for target shooting.
