How is it done?
Thanks, but I know about head space and the 'search' function. I hope I didn't put you through too much trouble.Here we go again .... a RIMMED cartridge head spaces on the rim of the cartridge, the rim is what controls the headspace ... simple
There is a great feature of the board and it is called SEARCH ... each and every forum on this board has on it right side of the main topic of the forum has a neat little feature called a SEARCH FORUM ... hit the little button and type in the word or words you are looking for then hit SEARCH and all the topics that deal with that topic pop up ... there is over over 19 pages of stuff regarding the word headspace on this forum.

The headspace on the Mosin is completely determined by the relationship between the bolt face and the rear surface of the locking lugs and the corresponding parts in the receiver/chamber. Even if the nominal tolerances are slightly out, most Mosin's pass a field gauge check, regardless of which bolt or bolt head is used. This is not absolute; there are sometimes bad ones. Ultimately, the rimmed cartridge system is the most forgiving of headspace tolerances. If the rifle you are concerned about was put together at an arsenal, and the bolt number matches, you have little to be worried about. If you need to be certain, get a field gauge.
A better deal indeed.http://www.amazon.com/Mosin-Nagant-...2038&sr=8-2&keywords=7.62x54r+headspace+gauge

To the best of my knowledge, there is nobody out there that makes ONE gauge that can make all three of these measurements.if a go-no-go field gauge (one gauge instead of three) tells you that you are OK (or not), then what would you need three gauges for?
