Been there, done that... with my tube-magazine, bolt-action .22 of 1968, which was the first firearm I ever owned with both powder and rifling coming into it. It had, perhaps astonishingly, all the intrinsic accuracy you could wish for, but was primitive and noisy to cycle, with a slow lock time, creepy trigger and sheet metal extractor. Believe it or not, those videos are an improved version.

If I had to do that firing-pin job again I would use a small taper pin reamer I have for the crosspin. A hard taper pin ought to lodge tightly without peening, and yet be easy to drive out. What I did was to bell-mouth ends of the cross-pin hole and slightly peen the ends of a soft pin. If you peen the edges of the hole over the pin, you can't smooth it off invisibly (one of the things Cooey did well), and you can't keep on doing it again.
