Hello Thehighroad. Been a while. First, I am not looking for a debate on whether or not guns should be shot or are tools or are supposed to be fired or any of that stuff. That is a personal opinion for each of us and not what I want to discuss. Second, I am not talking about five figure stuff or real antiques. I have collected S&W and Colt revolvers, mostly 1950-1981 stuff for many years. Most of them are in 98%-100% condition, and I have never actually fired any of them. I want to shoot a couple of them, but do not under any circumstances want to hurt their value(so obviously previously unfired guns in the box are out of the question). Example, I just got my hands on a S&W model 57. No box. Early 70s. 99% condition. There are extremely faint spin marks on the cylinder but I am not sure if it has been fired but without the box it doesnt really matter. How risky is putting one cylinder thru that revolver, say once a year or every other year? Obviously I would do it under perfect very controlled conditions. But how long do you think I could do that without affecting its overall condition? I am assuming that 500 rounds over a decade with proper cleaning and care and I will be ok. Is that a fair assumption? What you say?
