What does it mean when a revolver is "out of time"? How do I know if that is going on with my gun? Does it "spit" either powder bits or tiny fragments when fired? I thought I noticed something very, very small and hot hitting my face occassionally @ the range yesterday. Wasn't every shot and didn't seem consistent. Could it have been from the shooter next lane? He was firing an large caliber auto? Newbie question, I know, but would rather ask than assume anything. Thanks. 1970 S&W Model 19.
