Well, winter came and would NOT go away, then spring chores took up all the weather windows. FINALLY got out for a shoot to see if the gunsmithing really worked or not.
First observation is, the pin strikes on fired cases look nice and sharp, well-defined depth, too.
Second, I shot my best group ever with this rifle using Win PP 42s from the red boxes. Last summer, I was having misfires and pronounced vertical stringing, which told me there was a problem to begin with. So, for five shots, at 50 yards I plugged a .242 with the only, and last, five PPs I had. I guess I need to go buy a couple more boxes.
My usual CCI Mini Mags now shoot normally again, in the rough 8s at 50 in round ten-shot groups.
So, if you start getting misfires and other weird juju, check your firing pin travel/function/depth. Might be you just need some solvent, or some strategic Dremel work and stoning is also on the agenda.
Again, thanks for the help. It's like having my shiny new rifle all over again.
