| LCR .22 jamming cylinder
I've seen a couple of others mentioning jamming cylinders on their LCR's. Mine did yesterday when a friend was using it. It was his first time with a handgun and his technique was not good, so I was blaming him. I've fired over 500 rounds with no jamming problems and he fired less then three cylinders (24 rounds) and it jammed twice on him.
Today, I looked the LCR over very carefully and noticed a burr on the frame next to the indexing pawl. There is a sharp edge there. Closer inspection brought me to the conclusion that the indexing "star" on the ejector was cutting into that sharp edge and cutting a burr into the frame.
There was some powder debris caught under the ejector and this might be the reason. To fix the problem, I used a sharp instrument to remove the sharp edge on the frame (green arrows) and cleaned the debris under the extractor.
Will this solve the jamming problem? I believe it will, but time will be the judge.

22 revolvers also bind a little when they get dirty,you need to clean thouroughly and often.

This is a common problem with revolvers using dirty ammo (and most rimfire ammo is very dirty). Same thing happens to my Security Six 38/357 with cheaper target ammo. I have to clean behind the extractor star frequently when reloading.
Just a little particulate residue caught under the extractor star forces it to jam against the frame. You saw the results. Add tighter clearances as the gun gets hot and it is even more likely to jam.
One tip is to hold the gun with the barrel up when using the extractor to dump empty cartridges. This may help keep the soot and crud from getting behind the extractor star.

That indexing "star" on the cylinder should not contact the frame at any time and it obviously was on my revolver. There was a bright ring and it had actually cut into the frame and left a burr large enough to snag your finger on. Thus the reason I relieved that sharp edge. Hopefully it will clear now.

I've had the same problem with my son firing his Single Six - once the chambers get a little dirty (i.e. after one round), it takes a bit more force to fully seat the round. If you don't get it fully seated, it will eventually jam the cylinder.
