My friend got a Mosin Nagaunt at big 5 and brought it over for me to check headspace on. It closed on a No-Go- although it was tight. Is it still safe to fire?

Thanks

It is century arms import and has been headspaced according to CA. If it was tight on a no go it would not close on a field gauge and is most likely fine.

Stick your head under the table and wear a glove for the first shot. Not kidding.

Mosin Nagants and all WWII battle rifles should only be headspace checked with a FIELD gauge. They were designed with loose tolerances so they would continue to function in battlefield conditions.

If it's from Century and you're buying it from a first line retailer (like Big 5) you have nothing to worry about.

if you turn the bolt with one finger and feel resistance you're in very good shape. As previously stated those rifles chambers tend to somewhat...um...roomy. No need to worry until it swallows a field gauge.

If you forced the bolt to close, you might have ruined your no-go gauge.

People are WAAYY too spun up about headspace on old military rifles. That rifle sounds fine. Besides, most people just crank non-reloadable surplus ammo through Mosins. Even if headspace was slightly excessive, you're going to allow the cases to stretch a little, then throw them out? Where's the problem?

If you reload, and have slightly excessive headspace, you just back off the resizing die so a resized case "just" chambers. Excessive headspace solved by custom-fit ammo.

If you have so much excessive headspace you risk case head separations, you probably have such a worn bore, it's time for a new barrel, anyway.

In a Mosin Nagant you only need to swap out the bolt head to fix the headspace issues. No ammo or rebarrelling shenanigans involved. But yes, Mosin Nagants rarely have headspace issues even with mismatched bolts (unlike Enfields/Mausers of the same vintage).

IDK about the Mausers as the bolt heads are part of the bolt bodies, but with the Enfields, isn't that because there are different size heads (and some are for SMLEs and others for No.4s)?

New rule......If you cannot spell it, you cannot shoot it, lol. I have 8 Mosin Nagants. I always borrowed a go, no-go set of gauges from my friend at the gun shop. The first couple of times he told me not to force the bolt closed and ruin his gauge. Cas may have hit it on the head. None of mine ever failed. I haven't been shooting in 6 weeks, I'm starting to get the shakes, bugs crawling all over me, crazy thoughts, lol is this normal?
I need some range time.

You know it is all in fun. You need to get one, it will teach you the proper way of shouldering a rife, or beat you to death trying, lol.

I was referring to Mosins when discussing the bolt heads. Mausers, as mentioned, don't have such a thing. I forget about Enfields, it's been years since I sold mine off.
