not as yet. But I don't have any that have been road hard and put away wet! I started using the pins when I was taking machine shop classes, and had access to the inspection equipment. I started by measuring the barrels on Ruger 22 revolvers to see what they made the barrels at to be able to fire both 22lr and 22mag shells in the same pistol by swapping the cylinders for the convertables. then I decided to buy two pins for each of the dan wesson calibers, kind of go/nogo gage pins, now I think I need to go back and pick up the next larger size for each and also for the .375SM that I forgot along with the .32mag.
