I played with it a bit this evening. The bolt slides beautifully, if you push it forward straight from the back of the bolt.

I still have an old bottle of "Friction Block" PTFE. It was sold a few decades ago as a bore treatment.

I figured what the hell. It can't hurt. It seems to have slicked it up a little.

I already have 100 rounds loaded. I will get it on the bench and see if it is shootable at all.

If not, I know where a cutting torch is.

Thanks again for the advice.
