Gents, I have on order a 6mm BR rifle and will be using Lapua Brass. What dies (full size with and/or without bushing) do you recommend from your experience? I have no issues if you mix brands (sizer one brand and seater another)? fyi, I use a mandrel to open the brass case mouth in my reloading to control neck tension. I am using a Forster Co-Ax presently.
