Striker protrusion on Remington 1903

[rugersworld]

I recently bought a sporterized 1903 and the bolt face has corrosion and pitting. So I thought maybe the striker was puncturing the old corrosive primers back when the gun was first used and not cleaned very well. So before I shoot it, I would check the protrusion length. The striker firing pin on my bolt actually moves slightly forward and back, and the exposed amount is from 0.069" to 0.083". So, How far should the striker protrude?
Thanks for the help.

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?
