Re: fosrster vs rcbs dies
Unless you're going to a bushing sizer, or, and a Micrometer seater, I see no reason to swap them. RCBS makes a fine product.
I hate the Rcbs sizer with the threded rod sticking out, but it is still good. Hate flesh hanging off the thing!
So I usually buy their x-die if available.
So unless you're upgrading, you're just spending money, IMHO.
