Lee Undersize Carbide Sizing Die 38 Special / 357 Magnum

The Lee Undersize Carbide Sizing Die is a die-only solution for reloaders working with .38 Special and .357 Magnum cases that need a tighter fit than a standard carbide die will provide. The carbide sizer is sized .002" to .003" smaller than other Lee carbide sizing dies, bringing brass back down to spec for revolvers and pistols with tight chambers and ensuring consistent case-to-case uniformity.

Built around Lee's signature solid carbide insert, this die eliminates the need for case lubrication during sizing. The carbide sizer is ground to a special contour that does not leave a belt mark on the case, preserving the appearance of your brass. This listing is for the sizing die only; no shell holder is included.

Compatible with both .38 Special and .357 Magnum straight-walled pistol cases, this Lee undersized die is a practical choice for loading ammunition for vintage revolvers, target pistols with tight chambers, or any application where standard-sized cases will not reliably chamber. It also works well for bringing stretched, fired brass back down to factory dimensions.

Manufactured by Lee Precision in the USA, this die delivers the value and consistency that have made Lee a staple of the handloading community.
