Most posts to those 3 comms fail, but sometimes that’s lemmy errors. Anyway.
Rough Rider .22 revolver. Shells on the right are spent, left are unfired. Cylinder won’t rotate after the 3rd shot because the shells deform and poke up. Hell is that? It’s like they fire, bounce back and crumple, which doesn’t seem physically possible.
Sure seems like that’s happening when shooting it. Tested 5 cylinders, .22 and .22WMR, all the same results. Scarily, I can feel some back blast from the more powerful .22WMR, which again shouldn’t be possible.
Took it apart for some deep cleaning the other night, didn’t see anything weird, put it back together. Still fails. And this is the 3rd such gun I’ve owned, not my first rodeo.
I’m apparently banned in c/guns, c/liberalgunowners and c/asklemmy
Are you sure? There’s no ban that shows up for you in the mod logs of any of those communities.
looks like the gun part is missing. I hope I helped
I agree with the comments on this forum (https://www.thehighroad.org/index.php?threads/mushrooming-22-lr-case-heritage-rough-rider.891807/) that the cylinder could have a machining defect. (Basically a headspace issue, also but kinda not. The cartridges are sitting too deep in the cylinder itself.)
If there is room for the brass to get pushed back far enough for it to mushroom out, something is seriously wrong. The issue could manifest from a machining error as small as 5-10 thou, I am speculating.
My first thought was excessive chamber pressure, but the bulging would be much worse around and behind the rim itself if that were the case.
The bullet and the brass get pushed in opposite directions and if the brass can move, it will move before it deforms. If it deforms, it’ll deform at the weakest spot first, like we see in your pic. (Excessive chamber pressure tends to expand the brass and lock it in place. With center-fire, it’ll blow the primers out or have a hole punched in them from the firing pin first. With rim fire, the pressure pushes back on the rim.)
Also, check for excessive slop with the cylinder. If it can move forwards and backwards too much, that could also telling of issues with other parts of the gun. (Like I mentioned before, it doesn’t take much for a gun to be out of spec enough to cause issues with brass.)
This was my initial thinking as well. Could also be something loose in the cylinder connection that is allowing it to move and shift around side to side just enough to allow the brass to deform.

Can you dry fire it and rotate through every position? From what I’ve seen on revolvers sometimes a cylinder can be binding somewhere specific to the cylinder rotation.
You might also want to take every screw out of the frame to check and make sure none of them are broken which could be causing inconsistency.
I can dry fire and spin the cylinder all night long. Fucked with it watching a movie before and after cleaning it, will 5 different cylinders.
There is something wrong with the firearm itself. I’d contact heritage. Thankfully these guns are stupid cheap. So they might just replace the thing completely.
