Hello again. I am wanting to know if I have to F/L size a case every time I reload or just every time I load brass that hasn't yet been fired in MY gun? If I do it only on "new" brass, what do I use for my previously fired brass (ie:fired from MY gun)? Do I need a different type of die? I bought a 30-06 2 die set by rcbs, but are there more dies I need? I'm almost ready to start and I just want to make sure I have all that I need to do it right. I was under the impression that the brass that has been fired in my gun is now fire-formed to my chamber and no longer requires FL resizing.
