Measured my Odin Works bolt/firing pin and you are absolutely correct!! Rather disconcerting...
So if I understand correctly, if I want a replacement firing pin I need one specifically for 3.370?
Also how does the 2.800 bolt effect headspace? Can I only use bolts that measure 2.800 or would a 2.810 bolt with standard firing pin work?
