To understand what does removing the firing pin do for me?
I'm curious, too. Cocked, the mainspring tension will (on my son's bolt action) shove the bolt rearward making it difficult to detect any play. With the striker in the fired position on an empty case (no primer), I'd expect you could test for play--unless the firing pin bottoms on the primer pocket, in which case you could sacrifice a case and drill out the pocket. Perhaps it's easier to just remove the firing pin. Removing the pin on my .30-40 rolling block is easy enough.
