Lee Six Pack Pro Progressive Press Kit - .45 Colt .454 Casull

The Lee Six Pack Pro Progressive Press Kit for .45 Colt and .454 Casull (model 91907) is a complete reloading system engineered for shooters who demand precision and consistency across large-volume ammunition production. This progressive press platform automates the six-stage reloading cycle—decapping, sizing, powder charging, bullet seating, crimping, and finished round ejection—enabling trained reloaders to produce ammunition that meets exacting specifications in a fraction of the time required by single-stage equipment.

The kit includes a dedicated Auto Drum powder measure calibrated for consistent charge weights, a universal case feed magazine that maintains smooth feeding regardless of case geometry, and a complete set of Lee Breech Lock dies (full-length sizing, short charging, easy-adjust dead-length bullet seating, and factory crimp). The shell plate is calibrated specifically for .45 Colt and .454 Casull dimensions, ensuring reliable indexing and zero runout between stations. This combination supports loading both cartridges on the same platform without die changes—a critical advantage for shooters who chamber both rounds. The press weighs 18.94 pounds and occupies a compact footprint (11.25 × 10.75 × 18.3 inches), making it suitable for both dedicated reloading benches and semi-portable setups.

This kit addresses the specific demands of large-bore handgun reloaders: the .45 Colt and .454 Casull both benefit from careful charge weighting and bullet seating due to their lower velocity curves and sensitivity to powder variance. The progressive system eliminates the labor penalty of manual operation while the included load data and instructions provide the ballistic reference points required for safe ammunition assembly. Serious handloaders—including competitive shooters, hunting enthusiasts, and those maintaining firearms in these calibers—depend on equipment that produces repeatable results without requiring constant manual intervention.
