I have a .22LR nine-shot revolver made by NEF. Model R92. I bought it new many years ago.

The spent casings jam themselves into the cylinder. Enough so that I cannot push them out by hand. I have to hit the extraction mechanism against a piece of wood or something to force them out.

I cleaned the chamber and that didn't work... I took a .22 LR brass cleaning brush, chucked it up in a drill and slowly polished the cylinder and it still sticks.

I don't know what could be causing this... is it fixable? It's a decent little gun besides this problem...

When the gun is unloaded and the cylinder swung out, does the ejector rod operate freely?  Any binding?

No binding at all. That mechanism is fine.. the casings seem to be expanding and sticking in the cylinder.

Polish the chambers with some Flitz and a power drill. Polish that thing to a mirror shine.

The brush may be causing small abrasions which may or may not be what the brass is getting caught on.

My Pop had a High Standard Double Nine that was of similar metalurgy and quality.  His did the same thing, along with case splitting.  Look at your chambers with good lighting and magnification.  They are probably eroded.  


Hint:  A pawn shop will still buy it for about half of the original cost.

Might also trying to lightly oiling the chambers as well. This will keep them from being dry & perhaps smooth the ejection process.

Use a .25 caliber mop and some Flitz or Simichrome metal polish and polish them to a mirror shine.
Worked great in my GP100.

I'll try polishing it again and some lube but I bought some time...

I bought a Ruger SP101 .22LR tonight for the time being.

But I'll try those recommendations to get it going again.

Never oil cylinder chambers this will make it worse for best revolver extraction chambers must be dry.
Has it done this with multiple brands of ammo?

Never had an issue with a lightly oiled chamber & extraction......................    

+1. I do it all the time. I have an old Charter Arms Pathfinder with the same problem.  Helps a lot.

I've had the same problem with an older H&R revolver with a swing-out cylinder (which is probably pretty much the same as yours).

The chambers appear quite smooth, though I guess they could be undersized.

Anyway, I take a well oiled boresnake with me when I shoot it and periodically clean and lube the chambers.  That seems to help quite a bit.

You might also want to consider trying standard velocity ammo, if you haven't already.

Actually, what also really works nicely is using .22 Shorts.  However, nowadays they are pricey and hard to find.

When things start getting really sticky, I've loaded only six rounds instead of nine, which also helps.

While certainly not a Colt or S&W, H&R's (and NEF's) are surprisingly decent little revolvers for the price.  It's a shame they're no longer made.
