Re: More Dumb MG42 7.62 Headspace Questions

Thanks John, I emailed him, He has none? Thanks Pat Pat "He has none?" What does that question mean? You emailed him when he says he was closed for inventory? I'd probably tell you I didn't have anything either if you asked when the website says I'm closed for inventory. What did you ask ...

Re: More Dumb MG42 7.62 Headspace Questions

I have more time tonight: DQ1 The extractor should not protrude past the bolt face, therefore it will not affect headspace, which is determined by the rollers in the barrel extension grooves, and how far the barrel is screwed into the barrel extension (how far it protrudes into the inside of the ext...

Re: More Dumb MG42 7.62 Headspace Questions

I'm always looking for new manuals. I've seen a few that contained the information that is already in other manuals I've translated, so I won't do those because there's nothing new. If there's something new, I'd be happy to have more information. Manuals can be scanned (400 DPI or higher is preferre...

Re: Pricing of Original German MG42 8mm barrel

S300 would probably be the bottom price, with lots of rifling it goes up. Last one I had for sale was a year ago and I sold it for $280.

Re: Where to buy loose bolt head?

Right. Uh, the only guess I'd have for that request is that you'd have to send your barrel to the bolt head seller and have him check it with your gauge. There is no practical way to get what you're asking. Buy the bolt and take your chances, or take your barrel and gauge to Knob Creek in a few week...

Re: Make my own headspace gage?

I don't know what kind of reloading press and dies you have, but it's impossible to size the brass too small with my Dillon set up. The bottom of the die comes to rest on the shell plate. You can't compress past that. A different bolt head gives different headspace results. It would likely be all yo...

Re: Bolt stuck

The spring loaded pin on the bolt housing for the feed lever is an improvement that had nothing to do with your problem. Make sure the chips didn't come out of the cam surfaces. A dental mirror is good for checking that. If the cam surfaces are chipped, the cam needs replaced.

Re: Make my own headspace gage?

When reloading brass, an inspection before they are reloaded is necessary, especially if you're shooting in an MG34 or 42. Look for slight discolorations in a lengthwise line, or a slightly dark ring about 1/8" above the extractor groove. Brass can only take just so much strain before it separa...

" If I go to the Max Head Space in the 308 Gage, then I should be good for 7.62? " I have no idea. I never wanted to play with the tolerances like that. "Do you have any additional advice on how the rollers should feel when testing?" Rollers should go 100% outward. A little extra...

Re: Make my own headspace gage?

Cases stretch and shrink. They also compress, such as when they are resized in a reloading press. How many times it takes to do that (be resized) by being pushed into a chamber, which may or may not be worn or within specs, is anybody's guess. I suppose it would be good for at least one use. After t...

Re: TNW SA MG34 Failure to feed

I've seen the feed tray cause this problem before, that's why I suggested you swap it.

Re: Bolt stuck

Explain what you meant when you said: "Either way, 90% of the time it bounces back, sometimes it stays until I push the bolt carrier back in." The barrel bounces back so that it is in the forward position? Push the bolt carrier back in? In what? Do you mean you push it forward toward the f...

Re: MG42 - MG3 - M53 Build Help

There are many variations for a build. What condition the kit you're starting with, what equipment you have for building, and what you want it to be when you're finished (MG42? MG3? hybrid? M53?, firing pin style, receiver style) are all variables that make a single build link unlikely to match what...

Ahh, the ever unpleasant hakentt.

Saying that something "must" occur is only true under normal circumstances, without a mechanical malfunction.

His alternative method of getting the bolt unlocked may work and shouldn't damage the gun.

Re: Bolt stuck

If you can see the ejector bar, then that's not the problem. So, with the recoil spring removed, and the grip taken off, the bolt won't unlock from the barrel. Have you tried putting a block of soft wood (pine) on the ground and hitting the butt end of the receiver (gun held vertically) on the wood....
