This guide details the setup and operation of the Lee Load-Master progressive reloading press, drawing on expert instruction. It covers component identification, essential cleaning and lubrication techniques for smooth operation, precise die and primer seating adjustments, and proper assembly of the case feeding mechanism. The video emphasizes critical maintenance steps and operational rhythm for consistent ammunition production.

Quick Summary

Proper lubrication and maintenance are key for the Lee Load-Master progressive press. Apply axle grease only to the primer ram's saddle, avoiding the exterior to prevent primer flipping. The case feeder shaft must remain dry for proper function. Follow a precise 5-die sequence for pistol reloading and develop stroke speed in the middle of the cycle for consistent results.

Frequently Asked Questions

How do you properly lubricate the primer ram on a Lee Load-Master press?

Apply a tiny dab of standard axle grease exclusively to the primer ram's saddle. Avoid greasing the exterior of the ram, as this can lead to grease migration into the primer seating area, causing primers to flip or seat improperly.

What is the recommended die sequence for pistol reloading on the Lee Load-Master?

A common 5-die sequence includes: universal decapping (Station 1), resizing (Station 2), expanding/powder charging with a riser (Station 3), bullet seating (Station 4), and a factory crimp die (Station 5). Each die requires precise depth adjustment against the shell plate.

What maintenance is crucial for the Lee Load-Master's case feeder mechanism?

The case feeder square shaft must remain dry and unlubricated. This is essential to maintain the necessary friction for the mechanism to operate correctly and feed cases reliably into the press.

How can primer seating issues be avoided on the Lee Load-Master?

Ensure the primer ram is properly lubricated only on its saddle and that no excess grease gets into the seating area. Also, correctly adjust the primer seating depth using the contact bolt, starting with a small clearance.
