I am about to pull the trigger on upgrading to a Redding bushing resizing die for my 300wm. My question is that it seems that the expander button coming back thru the neck would negate the precision neck sizing that the bushing does. Also, I have to bump back the shoulder, so it seems I need the S Type FL Sizing die. Or I could get the body die to FL size and then use the Neck Sizing die to get the neck tension where I want it.
