I've read the manuals and lot's of instructions however a lot of them reference bumping the should back .002" from what a fired piece of brass is...what if I don't have any fired brass?
Well the just don't worry about it, as the will fire-form the first time you shoot them and then you can worry about setting the shoulders back. You do want to run new brass through the FL die so that the necks don't have any problems.
