Lee Undersized Carbide Sizing Die, 40 S&W/10mm

The Lee Undersized Carbide Sizing Die for 40 S&W/10mm (part no. 90787) sizes brass down slightly more than a standard carbide die, made by Lee Precision. Because carbide is so hard, no case lubrication is required, and the die actually burnishes the case as it sizes, leaving a noticeably improved finish rather than just a mechanically correct dimension. Lee builds these dies to last essentially a lifetime of reloading.

Frequently Asked Questions

Why would I want an undersized sizing die? An undersized carbide die sizes brass down slightly more than a standard sizer, which some reloaders prefer for a tighter, more consistent case fit.

Do I need case lube? No, the carbide insert is hard enough that no lubrication is required, and it burnishes the case as it sizes.
