I reread my posts and wish I could go back and rewrite it--I didn't correctly describe everything. Let me try again. the week before my S&W .357 magnum 686 L frame revolver broke, I the last 7 rounds I fired were Winchester 110 gr. hollow point. I fired them off and tried to reload, but one of the chambers would not accept the shell so i stopped and when I got home I found a shell casing broke in half inside one of the chambers. See Pic.--
Next week I was firing Winchester 157 gr. hollow point and the cylinder froze. It would not move, so I muscled it some and it started turning again so I shot 7 more rounds but then it froze again and wouldn't move. I had to get the range office to clear it and he looked and said the firing pin was gone, and showed be the blown primers on the spent rounds (same as them members here commented on). I took it to a gunsmith who said the ammo was the problem, he said they were reloads, which is what i came and posted.
Does the fact that one of the Winchester 110 gr. hollow point shell casing broke in half inside one of the chambers add any info to the discussion? See Pic.--
by the way, there was a recall of 686-6s about 20 years ago but I bought this gun in 2005--could I have a recall gun? There is no M stamped above the serial numbers, just "686-6"
