Striker protrusion on Remington 1903

[Patrick Chadwick]

The striker firing pin on my bolt actually moves slightly forward and back, and the exposed amount is from 0.069" to 0.083".

Surely the firing pin spring should have some preload? So when the rifle has fired, the firing pin (a.k.a. striker) is still pressed up against the inside of the bolt body. "Moves slightly forward and back" does not sound right to me. I would dismantle the bolt and check that there still is a complete and correct length spring inside - I once found two short springs one behind the other in a sporterized K98k that was scrapped. Maybe the spring was replaced by an incorrect spring (too short?) in the course of "sporterization" in a misguided attempt to lighten the trigger pressure.

Nevertheless, the range you quote for the protrusion seems somewhat on the large side. A plausible range is 0.055"-0.065". The real problem is if the bolt face is so corroded over the entire surface that the bolt has effectively become shorter, thus increasing the head space. How about a photo?
