OT - Sticky Chambers

[Rimfire McNutjob]

Paco's recent rimfire post reminded me that my Smith 648 has an issue. I assume I'm not the first person to have this problem so I thought I'd give it a shot here.

After firing about 3 or 4 cylinders of 22 WMR, the ejection of spent shells becomes problematic. My assumption is that the finish in the chambers is a bit rough and the brass sticks to the walls after the dimensions change a tiny bit as the gun heats. I had considered honing the chamers a bit but I can't seem to locate a 22 chamber hone. I would assume someone makes one that looks like a really tiny ball hone but for some reason I can't pin one down. Perhaps 22 chamers are too small and nobody makes a hone that small OR perhaps my search skills need work.

Anyway, would you guys attempt a light hone to solve this issue OR would you send something like this off to Cylinder and Slide to have corrected by experienced pros? The gun was made in the mid-90's which I think was when S&W was British owned and turned out less than stellar machine work. Not that being British owned had anything to do with the quality, but they did seem less than enthusiastic about the gun biz at the time.

I'm having the same problem, with a brand-new .22 Magnum DA revolver.

Load a cylinderful, fire all six - then no simultainous ejection via finger pressure alone.
In fact, I had to drive the ejector rod out to extract the empties - with three different brands of ammo.

I lightly polished all the chambers, using some emery cloth on a mandrel - but a retesting showed no improvement, so I shipped the gun back to it's Mom for warranty work.

Polishing chambers, using that method, can easily result in an out-of-round chamber, if someone inexperienced tries it.

I would speak to S&W's Service Manager about it - who knows ? S&W completely rebuilt an old, beat up, junker Model 41 .22 Target Auto, I had bought cheap & sent them when it didn't cycle properly - for the bubble.

I'd get a .22 mop and try some jeweler's rouge on it. Spin it slowly with an electric drill.

I hadn't considered that Rusty ... seems pretty reasonable. Though the machining marks inside the chambers look rougher than what a jeweler's rouge might take out. It's certainly going to be a gentler job that what a 400 grit hone might produce.

I may also call S&W and see what they have to offer as suggested by Pete44ru.

My Dan Wesson .22 has that problem.
I am going to take it to .22magnum,
I am assuming the re-chamber job will clean up the cylinders
