Stainless Pro Carbide Sizing Die 40 S&W/10mm

The Lyman Stainless Pro Carbide Sizing Die is purpose-built for reloaders working with 40 S&W and 10mm ammunition. This carbide sizing die streamlines the case preparation phase of the reloading cycle, enabling shooters to process brass efficiently without compromising dimensional consistency. The stainless steel construction paired with carbide sizing surfaces delivers corrosion resistance and extended tool life across high-volume reloading sessions.

Carbide sizing technology eliminates the need for case lube on fired brass, reducing prep time and cleanup—a significant advantage when processing brass batches in volume. The die's compact footprint (2 x 1.5 x 4 inches, 0.1 lbs) integrates seamlessly into standard single-stage or progressive press setups. Stainless construction resists the corrosive effects of primer residue and powder solvents, maintaining precise tolerances over thousands of reload cycles. The Lyman Stainless Pro Carbide Sizing Die meets SAAMI specifications for both 40 S&W and 10mm, ensuring resized cases chamber reliably across compliant firearms.

This die serves competitive shooters, law enforcement handloaders, and precision-focused reloaders who prioritize speed and consistency in case processing. Whether running range ammunition for training or precision loads for duty or match use, this sizing die handles both 40 S&W and 10mm interchangeably, eliminating the need for separate tooling. Serious reloaders value carbide sizing for the time saved and the reduced wear on press linkage from eliminated lubrication requirements.
