Redding Reloading Equipment Premium .40 S&W/10mm Special Neck Expander Die

The Redding Premium Handgun Expander Die offers a series of unique processes that ensure precision and performance during the reloading process. It begins with a radius on the base, which eases the entry into the case mouth for smooth operation. The die then features a parallel expander section that expands and trues the case internally, creating a perfect bearing surface for the bullet during seating. This process also contributes to a more uniform bullet pull and consistent start pressure. A small step follows, aligning the bullet with the centerline of the cartridge case to ensure it is properly positioned for contact with the seating micrometer, improving uniformity during the seating process. Finally, the die includes a flare at the case mouth, specifically designed to accommodate cast bullets, preventing lead shaving and ensuring a precise, smooth seating process.
