    I have a custom built 6mm I use for varmints and target shooting. I Found a bunch of brass in the back of my cabinet that I want to reload for test rounds. I'm gonna use the brass that is within .005 of each other. Should I fire form them before getting serious with my loading. I'm not sure if they were fired from my rifle or not. I'd hate to waste the time tweaking loads if this is the case.
