Neck Sizer Dies resize only the neck of case just enough to snugly hold the bullet. This leaves the shoulder and body at their fire-formed dimensions which leads to longer case life and increased accuracy. For use with bolt action rifles only. New brass must be full length sized and fired before it can be neck sized.
Set includes a Neck Sizer Die with Expander-Decapping Unit and a Seater Die with Seater Plug. Shellholder sold separately.
