I am curious, Mosin Nagants headspace on the rim, this is because the Russians didn't have the tools to properly machine the chamber, and to keep costs low. It also allows the use of different ammunition, without having to rechamber the rifle (original ammo was lead round nose). So my question is how is head space important if it spaces on the rim. Believe me I know headspace is important which is why I have go/no go gauge for the m2 on my keychain.
