Marlin experts...Extractor issues

[novalty]

Last year I started having problems with the first rifle I ever owned--Marlin 882. I love the rifle dearly, and it is very accurate, even with a cheapie scope. The problem I am having is extracting spent cases. I have always fired CCI ammo in the gun, but I tried a box of Winchester Dynapoints, they kept getting stuck in the chamber. I watched the extractor and it would walk up over the rim of the shell, and leave it in the chamber. My first thought was that the rims of the Winchester Dynapoints were out-of-round, and extractor was only getting a grip on the shells with enough rim for it to grab. My second thought was that the extractor or chamber was dirty. Tried cleaning still same issue, will extract spent cases very infrequently. So I bought some more CCI's, loaded a mag, and cycled the live rounds. It loaded and extracted all 7 rounds without issues. The other day I took it out to eliminate a grey squirrel that had been living well off some birdseed, gun loaded and fired fine, but had the same problem extracting the shell. Is there a way to adjust the tension of the extractor, or is there some other underlying issue? I can't find any flaws, in the extractor hook, and it has been thoroughly cleaned. Any suggestions or idea would be greatly appreciated.

There might be a burr or spot on the edge of the chamber from dry firing. It does not take much of a burr to lock the fired case in the chamber tight enough to overcome the spring tension of the extractor.

Can you see anything similar to the small dent on this fired case?

I will check tonight, as I saved the last case fired. The cases do feel very tight in the chamber, when I have to manually extract.

As a high mileage gun, the extractor may be getting tired. Is it the new style one-piece extractor? You could try replacing it.

You should be able to visually see if the firing pin is hitting the edge of the chamber and turning a burr into the chamber. Not uncommon on alot of rimfires.
The firing pin is supposed to be setup to fall a few .000" short of striking the metal edge of the chamber when dry fired,,but still has enough travel to fire the cartridge.

Sometimes they are just not set up right,,sometimes wear in the parts allows a bit more forward movement over time and it only takes a few strikes to imprint the burr into the chamber edge.

If it's there..carefully stone or polish it out of the way. There are tools made to push the displaced metal back into place.
Avoid dry firing and even shorten the firing pin a very few .000" will make sure it doesn't happen again.

If that model still uses the one piece spring clamp extractor, there isn't much that goes wrong with them. That style hasn't changed much since before WW2. Unless it's bent out of shape and loose on the bolt head, or obviously chipped or broken, they don't cause much of a problem. Most of the damge to those comes from owners attempting to remove and re-install them for what ever reason.

The old style spring wire ejector was the biggest problem part in the older '80 models. I'm guessing they got rid of that by now.

This one was purchased new back in the early '90s. I don't dry-fire the gun, but burr could have arisen from wear--although I don't believe I have put more than 250-300 rounds through her. I checked the spent shell casing of the last round I fired and it didn't show any dents or imperfections anywhere. The extractor has never been played with, and feels very firm. Quiet frankly, I can't determine why it would ride up and over the rim. Thinking maybe I need to plug and soak the barrel in Break-free. The only other thing that I can think might be causing issue is the clip, it is the original one, and has had cartridges left in it for extended periods of time. Wondering if maybe the spring or lips of the clip are allowing the cartridge below to tip enough and block the extraction of the spent case.

Without seeing it, only a guess, but perhaps try replacing the extractor???
