The Lyman 2-Die Rifle set for .300 AAC Blackout features a full length sizing die and a bullet seating die with roll crimp. Lyman uses computerized milling equipment to insure that each die is perfectly dimensioned. The sizing die is vented to prevent trapped air which can damage the case. The dies are polished, heat treated, and then micro-polished to perfection. Industry standard 7/8x14 threads means they can be used on all popular reloading presses.
