39a Failure to extract

[Mal H]

It worked!

I fired 10 Lapua shells with no prep done to the cases, and every one of them ejected. In the past, I would have had at least 3, usually more, FTE's out of 10 using that particular ammo.

I still have to do some tweaking of the ejector angle because the empties now come out a little more lazily than I would like. They eject only about one or two inches as opposed to a good foot or more with "normal" ammo ejection. But, having them all come out without having to dig them out of the chamber with a small screwdriver is a real victory.

It worked!

I wouldn't lie to you.

You guys are giving me some concern here. I just ordered a new 39A yesterday. Kind of a pricey 22, but I've wanted one for a long time. I'm sure hoping not to have extraction problems righth out of t he box. What does Marlin do to theae rifles when they're sent in for extraction problems?

For my rifle, nothing.

But it's a hell of a lot easier to do what I described and illustrated above, than it is to send the gun off, anyway.

Don't sweat it. Just check your extractor like you inspect other things when you clean the gun. It's not a big deal if you know what you're looking for.

You should also make sure the internal screws are tight when you clean the gun.

I consider this stuff simple maintenance. The 39 is a great rifle.

Many will probably think this is heresy:
I have helped the reliability of quite a few non match grade 22s by using a bore mop thoroughly saturated with JB Bore Paste. I just run it in and out of the chamber with an electric drill at medium speed for about 30 seconds. It polishes the chamber and the lead into the rifling.

I have even done it on Volquartsen and Green Mountain "match" 10/22 barrels that would not feed reliably. Notwithstanding VQ's claim about precision chamber reaming, after I "mop honed" them they were very accurate and fed reliably.

My theory: there are a lot or microscopic burrs left after chamber reaming including at the entrance to the chamber. The JB paste is a very mild abrasive and I think it cleans these up. Also, a slight chamfer on the chamber entrance helps; I mean slight like about .005 radius so as not to interfere with ignition.

Armed Bear,

It worked!!!!!!!! I tried the new extractor from Midway without tweaking it and had the same results. Then I tried out your idea. Bend, insert a shell, bend, insert a shell, trial and error. It only took around 20min. I went outside and ran about 200 rounds through it without one single FTE with different ammo! I don't know If Marlin is having a manufacturing problem with these newer extractors or what but I've got an older 39a I've never had issues with.

Thanks to everyone for their ideas and help,

Glad to hear it!

I don't know for sure, but it's looking like Marlin doesn't even KNOW about how to solve the problem.

As I said, my rifle went back to Marlin TWICE and came back the same. Their CS people were really nice, and it does not seem to me like they just blew me off. It seemed like they didn't know.

Maybe their 39 expert retired or something. I really don't know.

I'm thinking I'll send them this info and pics, too. I just wonder about the proper channels so this actually gets to their 'smiths, not some sales weenie.

Success ! This was just the ticket for my 1897 Texan, now its extracting and spitting out spent cases like crazy !

I can hardly believe how little the extractor grabed the case before i modified it.. Just a tiny, tiny portion at the very end of the rim was being engaged by the extractor "claw".

Great Forum !
