Lee Precision Pro Auto Disk Powder Measure - .50 lb Capacity

The Lee Precision Pro Auto Disk powder measure is a high-volume rotary charge dropper built around Lee's proven rotating-disk design. Interchangeable metering disks deliver consistent, repeatable powder charges without the cut kernels or sticking that plague ordinary measures, making it a go-to upgrade for handloaders running high-volume batches.

The hopper holds up to .50 lbs of powder, enough to keep a progressive press fed through extended loading sessions. An elastomer wiper paired with a Teflon-coated metal casting keeps powder flowing smoothly through the measure, virtually eliminating the cut powder and bridging that disrupt charge weights. The assembly combines steel and nylon/plastic components finished in Lee's signature black and red scheme, with the entire unit made in the USA.

The Pro Auto Disk is infinitely adjustable between approximately .28 cc and the maximum throw of the chosen disk. It accepts the full Lee Auto Disk family of metering inserts and is rated for cartridges from .22 Hornet through .308 Winchester, with documented use on common pistol loads including 9mm, .40 S&W, and .45 ACP.

Engineered primarily for use with Lee's Pro 1000 progressive press and compatible with Lee turret presses, the Pro Auto Disk is a fast, repeatable charge-dropping system for high-volume pistol and rifle reloading. One Pro Auto Disk powder measure is included.
