Lee 90039 Lube & Size Kit for .311 Caliber Cast Bullets

The Lee 90039 Lube & Size Kit provides a practical solution for lubricating and sizing cast bullets during handloading. Designed for .311-diameter bullets, this kit helps produce consistent bullet dimensions for improved fit and reliable performance. It can also be used to seat and crimp gas checks, making it a versatile addition to a cast-bullet reloading setup. Lee Liquid Alox and a compatible press are sold separately.
This kit is intended for use with single-stage presses and features a standard 7/8-inch x 14 thread pattern for broad press compatibility. Bullets are pushed nose first through the sizing die, eliminating the need for specialized nose punches. The included push-through punch takes the place of a shell holder in the press ram, while a dedicated container captures the sized bullets as they exit the die. This nose-first process supports efficient sizing while helping protect bullet noses and profiles.
For cast bullets, Lee recommends selecting a sizing kit approximately .001 inch larger than the barrel groove diameter. The steel components provide dependable service for repeated reloading tasks, and the silver finish offers a clean, functional appearance. The kit includes the sizer box, sizer punch, and sizer die, along with instructions to help users set up and operate the equipment correctly. Built specifically for cast-bullet preparation, the Lee 90039 kit is a useful choice for reloaders seeking a straightforward way to size, lubricate, and prepare bullets on a single-stage press.
