Just picked up a new .300 WM and though I would jump into the world of Redding type S comp dies over the RCBS dies I normally use. My question is when using new brass am I going to need a to get a stand alone die that has a expander button to get the case necks round so they can be loaded the first time? The dies I have don't have a expander on the decaping pin. I understand the reasoning, just not sure how to go about it for the first loading.
