It has been a long time since I was a gunsmith but I never saw a .22
rimfire firing pin that had any sort of "stop" built into it -- this
is not to say that things haven't changed since I was in the business

It has a stop: The pin is "T" shaped, with the vertical leg being the rim-striking portion, and the top of the tee a larger block that impinges on the side of the barrel, to prevent over-penetration (I guess).

but why not mic some quality ammo rims and some "bucket of bullets"
rims. That should tell you right away if rim thickness is the problem.

Did my description, "cheap, thin rounds" go wasted?

CCIs are about 4-thou thicker in the rim than the Federals that fail.
