Re: Head spacing a Mosin Nagant after fixing a broken bolt
Using the same brand of headspace gauges that sharpie used, we sat down and checked 7 different Mosins, ranging in receiver dates from 1896 to 1954. All checked out within specs.
Then we took one bolt head and tried it in the other 6 rifles using their respective bolts. All still checked out within specs.
Pretty impressive considering a 58 year span, and the primitive machinery and conditions they were built on. Two of these were wartime 40's production, when the Russians packed up and moved entire factories back from the German lines.
