It's actually in inches, .075" and .095". Russia was only converted to metric by the Soviets in the 1920s.

The slot has to be indexed with that mark because of the safety system. There's a rectangular section of the firing pin that matches a rectangular channel in the bolt. You apply the safety by pulling the cocking knob and turning it to the left (similar to decocking). The finger on top of the bolt will rest on the flat on the left side of the receiver. This locks the bolt shut and rotates the firing pin out of alignment with it's channel so it won't reach the primer. Very positive but hard to do and slow to apply and take off.
