SVT 40 headspace

pmr1010 · 05-07-2012, 08:09 PM

I recently picked up an all numbers matching SVT 40 for a good price. Good bore and good wood, but the metal is perfect! Really perfect. Not replacement parts, they're all arsenal marked and match the rest of the rifle's markings.

But when I checked the headspace with PTG gauges it closes on a NoGo gauge. Not easily, I have to help it but not too much. 1 finger push I would estimate. Now to be honest, I have checked other Russian rifles that failed with 1 gauge or another and passed a bullet test. I admit I also fired them with so far so good results.

Can anyone add any input regarding headspace gauges and my issue here? Please!

Gunboards.com has a lot of svt folks in the collector's forum section it if you have not visited. A lot of info on the rifle and worth joining. They can def.answer. You might already know this though. I have never checked mine but it passes the fires and reload test with accurate results! I bet you are fine. Now show some pics!!

It sounds like it’s getting close. But you are probably OK. The Go and No go gauge is more or less for Gunsmiths that build or repair these things. A field gauge is what you need to check them for safety. They are slightly longer than a No-go

BTW
You are better off posting these types of questions in the Gunsmith section. I almost missed it. And obviously everyone else did.

If you haven't already it would probably be worth your while to go check out Survivor's SKS boards:

The folks over there have a pretty broad knowledge of Russian milsurp firearms. They're a good bunch.

If you do get to fire the rifle, check the spent cartridge for signs of primer stick out of its pocket and case bulging near the rim.

At any rate the use of the gauges is the way to go, safety 1st.

I did check with a field gauge and it did not come even close to closing. Must be right on the edge for the No Go, but well within for the Field Gauge.

I'm taking her out Thursday for some peace and quiet at the range.

Bring a wrench or something to adjust the gas system.
And as i stated in the other thread, hopefully you have some differnt makes of ammo, if shooting surplus.
