Ok, I use stainless pins with remarkable results on my brass, I got a phone call from a few fellow reloaders who tell me that you can only use the pins one time on brass cases because the pins remove brass and will cause them to split or prematurely wear out. I have never heard this and was wanting you fellas input on the subject. What they are saying is that you have to keep track of the brass that has been through the pins and not to tumble the same ones again in pins. Any comments are appreciated.
