The sticky firing pin did not help but was not the complete answer.
Pulled the bolt completely apart again.
Noted that both ends of the firing pin spring were a bit ragged, not dressed.
Also found that one end appeared to have been unwound a bit and was oversize for OD so probably also binding.
I had no spring stock to replace this one with so I dressed the ends and made a new one of the #15027 "Firing pin spring follower" that was about .250" longer above the spring.
That added enough spring pressure that the gun now shoots just fine.
So all it took to resolve this one was time, fine files, dremel tool, a lathe and three trips to the range.
