I have a chipmunk 22 LR that the chamber is tight on. if I force a round in the ejector will not pull it out. Is there something I can do to loosen the chamber up. I have tried cleaning it real well to see if there was just a lead buildup.

Thanks,
 
I had the exact same issue. Which was weird, because it was fine, then, all of a sudden, it wasn't. Tried everything I could think of, cleaning, different ammo, etc. Finally gave up, put a piece of 800 grit sandpaper in a cleaning eye, chucked it in a drill, and reamed it for about 15 seconds, IIRC. Took the sandpaper and eye out, chucked a bronze bore brush, and ran it for about 2 minutes. Feeds everything now.

That did the trick. Thanks!!
 
Chamber honing also works well. You can buy them off Amazon in different grits and for rifferent cartridges like .357, .44, .45 etc. I honed the chambers of my rimfire revolvers and I rarely have an issue with sticking cases (Aguila bulk ammo excepted. That stuff ALWAYS sticks :fire:).

Glad you found a solution!

Stay safe.

I saw a 22 magnum hone on amazon. do you think that would work for 22 LR as long as you didn't insert it to far?

Thanks!!
 
I looked
Yeah, look for the proper one. Flex Hone sells them in their site, that’s where I got my .45 cal one for my .45 Colts.
I checked their Websight and doesn't look like they have one for 22 LR. I have polished the chamber to where it will work with Remington and federal ammo. I measured the diameter of the rounds and Winchester is .25 inches and the others are .24 inches. The Winchesters don't fit.

Hmm. I checked and the ones I used were marked for .17 cal/.22Mag. I thought it was specific, but they’re flexible so I guess they compress into the LR chamber to polish them. (you aren’t cutting a chamber with a reamer, just polishing it.) Using oil to lube and a drill press to spin, a light pass or two was all that they needed. The honing did magic for the chambers in several guns, Models 617, 48, 48 and 34, along with a Dan Wesson and four Ruger single actions. Zero sticking and no affect on accuracy, reliability, split cases, etc.

Now Aguila Super Extra bulk-pack rounds still get stuck in my handguns, which is a bummer because I have about 3,000-4,000 of those left to shoot. The bullets and the cases seem to all be a bit oversized.

Keep using the ammo that works and the chambers clean, and you should be good. If stuff starts sticking again, then maybe try a hone. :thumbup:

Stay safe.

Your chamber may be different, but often w/ .22, there is no relief under the firing pin. If you dry fire a few times, you peen a burr in the chamber wall that will hang cases. First, try not to dry fire a .22 without a snap case. Second, if you have the problem again, look closely at the chamber rim. Often you can find the peened area and just work that one spot out.

What badkarma gave you works well, just beware of doing too much of it or you might start to have misfires. This because you loose support under the cartridge rim where the firing pin needs to have an anvil to set off the pressure sensitive powder loaded in the case rim - I.e., rim fire.
