need headspace guages

[Ratfood]

Hi does anyone know who makes headspace guages that I can use in a mosin nagant without taking out the extractor from the bolt.
Thanks!

Good question, Ratfood. I'm looking too.

Anyone,..anyone? Bueller?

In spite of many postings by folks who claim that leaving the extractor in will mess up results, cause a nuclear blast, or result in some other calamity, most gunsmiths don't remove it. They just slip the gauge up under the extractor and guide the gauge into the chamber. Some extractors will exert sideways pressure on the gauge, but the oft-repeated caution seems to be intended to warn against chambering the gauge and then closing the bolt on it, which on some rifles will harm the gauge.

(Note that there is a very real reason for removing the EJECTOR on rifles that have plunger type ejectors in the bolt face. If the gauge does not have a cutout, those ejectors should be removed as they will give false readings. Also, removing the firing mechanism is a good idea, but is only necessary for cock-on-closing rifles, where the force required to close the bolt will give a false reading almost every time.)

Ummm, so ..... I want to use these for a mosin nagant... Does this mean I don't worry about the ejector and just use it anyways?

Thanks~

Can you not get Headspace gauges with a cut out for the extractor? all our new ones have it (5.56)

I buy up Mosins whenever I find good ones, half a min and I'll find the receipt for my gauges and let you know where I got them.

Midway has em, go no-go albeit at a higher price than I approve of.

Also, the Russian Mosin Nagant homepage http://www.russian-mosin-nagant.com/ is a wealth of info for the collector.
