I have been reading up on the Redding body dies for a couple of weeks here and there now and don't know that I understand the full utility of this die or what the ultimate goal of using it is. I understand that you are sizing the shoulder and the body and not the neck. It seems that the objective is to use it once the brass gets a little "sticky" and difficult to chamber, but I know there has to be more to it than this. Are ya'll using this on every reloading cycle or just after every couple of reloads? Any insight is appreciated.
