OK, picked up a high sn# 1903 made in 1917.
I'm looking at this, trying to understand the geometries of the bolt and stuff.
Looks like the lugs themselves are squared off, so no camming forces applied there, but the safety lug (the third one towards the middle of the bolt) appears to be slightly ramped, and all camming force for the bolt is applied there against the reciever? Is this right?
Primary extraction appears to be handled by the bolt handle where it meets the body of the bolt (yeah, I know its one piece, but it was the best description I could come up with).
I'm not seeing any obvious way to manage firing pin protrusion in the design of the 2 piece FP. Is this possible? What should the protrusion be?
Thanks.
