Lee Precision Lube & Sizing Kit .410" Cast Bullet Sizer 7/8x14

The Lee Precision Lube & Sizing Kit is a complete cast-bullet sizing station for .410 diameter lead projectiles, designed to mount in any standard reloading press with 7/8"-14 threads. This compact kit lets the home reloader lubricate and size cast bullets in a single, repeatable operation without purchasing a dedicated lubrication machine, and it also works as a handy slug sizer for the Lee Load-All.

The kit includes three matched components: a sizer box, a sizer punch, and a sizer die cut specifically for .410" diameter cast bullets. Hardened steel sizing components ensure a uniform diameter and a smooth finish on every boolit, while the molded red plastic sizer box holds the bullet steady during the operation. The die screws into any standard 7/8x14 threaded reloading press, so it drops right onto the same press body you already use for loading.

Operation is simple: drop a lubricated cast bullet into the sizer box, run the press, and the sizer punch pushes the bullet through the die. The bullet emerges at a uniform .410" diameter, and the same stroke can simultaneously seat and crimp a gas check for reduced leading and improved accuracy. Whether you cast your own pistol or small rifle boolits or load for a 28 gauge Load-All, this affordable kit delivers factory-quality sizing with minimal setup and cleanup.
