Rossi 511 .22 problem

I recently acquired a Rossi 511 .22lr revolver on GB that I am having a problem with. First, I'll start with the fact that I love this little shooter. I would love it more if I didn't have a problem with it.

The problem: after a round or two, the trigger becomes very hard to pull. Almost impossible. And I can't cock the hammer. Any attempt to pull the hammer or trigger feels like a grind.

I can open the cylinder and close it and I can finish the rest of my rounds.

From trying to visually inspect what is going on, none of the spent rounds seems to be misshapen to the point of impairment. And the cylinder appears evenly spaced. I have cleaned it and all of the rounds rest flush in the cylinder. I've tried it with three different brands of ammo with similar results.

Any ideas for this novice? If there is a picture that would help or some simple test I could perform that would help diagnose the issue, let me know and I'll report back.

First thing I'd check for is excessive wobble of the cylinder at the rear. That can cause the hand to bind against the ratchet star. Then check the tip of the hand for mushrooming which can also cause binding. If that ain't it it's time to open her up & check the guts for gunge, broken bits, or binding. Lack of lubrication can also cause binding or gritching of the works, particularly the hammer.

I also have a .22L.R. revolver, in my case it's a 6'' Weihrauch. I always carry a teethbrush with me in my range trips to keep the whole zone under the ejector star totally clean and dry; I also brush the counterbores and chambers to allow the rounds to always go in full battery ; I inspect the zone around the firing pin and I keep it clean; I use the brush every 100 or so round to prevent problems or when I feel something is not working 100%.
Another advice could be try different ammunitions and choose the ones with the thinest rim.
If these tricks don't help it could be the cylinder that snags against the shield after the first shot due to excessive endshake (my revolver has a spring in the yoke that keeps the cylinder always in its forward position to prevent this issue).

Hope this helps. Best regards, 5-SHOTS.

I'll head back to the range and take a close look

Took it back to the range and still having problems, though fewer than the first time. Tried three types of ammo (CCI mini-mag, remington yellowjacket, and federal bulk hp) and they all had signs of the binding problem. Had a guy that works at the range take a look and the cylinder wasn't loose and the timing was good. No signs of metal shavings. No buildup under the extractor....other than taking it to a gunsmith, any other suggestions?

How's the B/C gap? Sounds tight to me....check it with a feeler gauge. Or it could be excessive cylinder play. Some with steady hands and a fine file adjst the former themselves,the latter may be adjusted making bearings out of feeler gauges to set back the cylinder to spec.

At this point seems to me that the forcing cone or the cylinder's face develops leading after very few shots because of too tight gap or imperfect alignment between the chambers and the barrel.

Is your ejector rod screwed-in tight?
