Lee Auto Prime Kit* -

The Lee Auto Prime Kit represents a significant advancement in reloading efficiency, designed for shooters who demand speed without sacrificing accuracy or consistency. Whether you're a competitive reloader, law enforcement armorer maintaining duty ammunition, or military-trained reload specialist, this kit eliminates the repetitive hand-priming bottleneck that slows production on high-volume sessions. Auto-priming systems reduce fatigue and standardize primer seating pressure across every round, critical factors when processing hundreds of cartridges for training cycles or match preparation.

The Lee Auto Prime Kit includes the innovative Auto-Prime mechanism paired with eight interchangeable shell holders covering the most common rifle and pistol cartridges—encompassing over 130 different load specifications across standard caliber families. The shell holder system accommodates eight pre-installed sizes (positions 1, 2, 3, 4, 5, 11, 12, and 19) while the kit frame holds capacity for an additional 10 holders, allowing modular expansion as your reloading library grows. This modular architecture means you're not locked into a single caliber; operators can quickly swap holders between 9mm, .45 ACP, 5.56 NATO, .308 Winchester, and specialty cartridges without tool changes or setup delays.

Professionals running high-volume ammunition programs—range officers, department armorers, and precision rifle teams—benefit most from the Auto Prime Kit's repeatability and throughput gains. The compact footprint (4.45 × 1.75 × 6.8 inches) integrates seamlessly into existing Lee progressive or single-stage press setups without requiring dedicated bench real estate. Compatibility across 130+ cartridges and the expandable shell holder design make this kit the foundation for scalable, long-term reloading operations where consistency and speed directly impact training readiness and cost per round.
