22LR Revolver Cylinder Tight

[haze10]

I have a Rossi revolver and the cylinder chambers are tight and won't accept cartridges without a lot of pressure.

If I wanted to ream them myself what reamer would I need, throat or finish, and how do I do it.

Do you know of a hunsmith that performs this service.

Dumb question: are you sure there isn't carbon buildup in there fighting the case going in?

I might try using a .22 NYLON bore brush dipped in polish (like chrome polish) and spin it with a hand drill in the chambers.

Where are you located? That will affect your choice of hunsmiths. You would need a finish reamer if you want to do it yourself.

How old is the gun? If it is an old gun, it may be chambered for .22 long, not .22LR. that would definitely cause the tightness loading .22LR.

Has it been dry fired much?

Check the cylinder for a dent from firing pin strikes, you can also check your fired cases for a line running the length of the case

If you find that, brownells sells as swaging tool to fix it

I have an older model 17 that I would have a lot of trouble getting the empties to extract when just a little dirty. I solved the problem with a reamer from Brownells. The box says 22LR Cylinder Finisher Reamer #513-051-220. You will also need a T handle and some cutting oil. I'm not a hunsmith but it wasn't that hard. Wet the reamer well with cutting oil, cutt then blow out the chips in the chambers and the blades of the reamer, add more oil repeat. The reamer depth is limited by the primer lip recess in the cylinder.
