I want to check headspace on my M39. The thing with the gauge for doing it myself is that I was told that it will be 3 to 4 weeks for delivery as I opted for the coin type from a company in Brockton, Ma. However, I may just buy from Midway USA or Brownells for the cartridge type because it'll get here sooner.
It wasn't a matter of them not having 7.62x54r calibers, they simply have no gauges at all. When I asked about using dial calipers or micrometers they told me they don't check headspace.
I did not try Stateline in Mason, but did try stateline in Plaistow, who told me about "redneck headspacing". I'm exagerating a bit when I say I called all of them. I only called about a little over a dozen. Lewis, Rileys, Stateline, Costa, Daves, Collectors & others
I am going to order No-Go & Field gauges & just wait. I was calling shops so I can just go shooting sooner. I have butterfly's in my stomach over this rifle
