Lee 90054 Lube & Size Kit, .429 Caliber Bullet Sizer for Single-Stage Presses

The Lee 90054 Lube & Size Kit provides a practical way to lubricate and size cast bullets while preparing them for reliable loading. Designed for use with single-stage presses, the kit includes a sizing die with standard 7/8-inch x 14 threads, making it compatible with many common press setups. The .429 caliber sizing configuration is intended for cast bullets that require consistent sizing before loading.
Bullets are pushed through the sizing die nose first, 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 arrangement helps keep the sizing process organized and supports efficient processing of cast bullet batches.
The Lee 90054 kit includes the sizer box, sizer punch, sizer die, and instructions. For cast bullet applications, Lee recommends selecting a sizing kit approximately 0.001 inch larger than the bullet's groove diameter. The steel components feature a silver finish and are built for use with cast bullets. Lee Liquid Alox lubricant and the single-stage press are sold separately, allowing you to select the equipment and lubricant suited to your loading setup.
