The Lee Precision .30 Carbine Powder Through Expanding Die (Lee part no. 90494) expands and flares the case mouth of .30 Carbine brass while doubling as a powder-charging station when paired with a powder-through expander setup. Flaring the mouth just enough to seat a bullet without shaving lead or jacket material is critical on straight-wall brass like .30 Carbine, and combining that step with powder charging saves a station on a turret or progressive press. It threads into any standard press and is built for reloaders who want a streamlined, repeatable process for .30 Carbine ammunition.
