My Redhawk used to do that, cylinder would bind with my reloads...it had a pretty tight cylinder gap, I think it was .004 - .005. I opened it up a couple thousands. I think I made it around .006 - .007 and it has never had the problem again
That been about 30 years now I guess...wow...yep I've had it a looong time and it is still a fine shooter.
I love that big old beauty
