never had one, don't lube the front of the cylinders, sometimes use wads sometimes not, but I believe if you have a nice ring from your ball showing the front is sealed, your nipples are snug and the holes the right size, you should be ok. There is a "oops" factor in everything, factory loaded ammunition sometimes doesn't work like it's spose to. I think if you are cognizant of the fact that any gun is potentially dangerous, and handle it with respect, in the event of a mishap like that you will prolly be o.k. Those fellas who are vets prolly have experienced a "runaway gun" once or twice in their lives, lol!
