A bit ago I had purchased some steel cased 357 ammo and after one or two rounds it seemed to lock up my revolver. The fired cases were stuck back against the frame and I had to open the cylinder and force the swelled cases out. At this time I put the unfired rounds back in the box and gave that stuff away to another member here. Ever since this incident my cylinder has been "sticky" to open or close, which I assumed was a speck of metal somewhere inside the gun making a pain out of itself. I figured someday I'd get a gunsmith to deep clean it and fix the problem. Well today I said I'll just watch some youtube guys and figure it out. After some time I didn't find anything that related to my malfunction and at this point it wouldn't close at all. After some beating of my head against the desk I found that my ejector rod was partially unscrewed and a simple tightening (left hand thread by the way) had everything working great again. I wished I had asked someone here for advise but I was really convinced it had to do with that steel cased ammo.
