The “Modular Sizing Die” uniquely sizes the cartridge’s body geometry with the die body, while a “Neck / Shoulder Bushing" handles the shoulder and neck geometry. This allows one die body to work for the entire cartridge family.
Our Modular Sizing Dies focus on properly sizing your fired brass. These dies size the cartridge base slightly more than the shoulder, enhancing performance.
After studying precision CNC machines and tooling, we designed the Modular Sizing Die to center and secure the Solid Decapping Pin with shallow tapers rather than threads. This tapered geometry provides unmatched concentricity and repeatability.
We designed the cartridge sizing geometry to size slightly more at the base and slightly less at the shoulder compared to most resizing dies. For properly sized rifle chambers, this helps avoid extraction issues with fired brass and reduces case runout by minimizing over-sizing of the shoulder.
