I've got a Mosin M-44 "carbine" that is light striking the primer.

How far should the pin nose protrude from the bolt face?

How is this measured?

When I pulled the bolt down, the firing pin was screwed all the way into the knob. The pin nose was just barely touching the primer when fired.

I would think that once the pin nose protrusion is set, the firing pin spring preload would hold the adjustment, am I right?

Thanks, Paul
