The Lee Precision Pro Auto-Disk powder measure is a workhorse accessory for serious handloaders who want speed without sacrificing precision. Designed for use with Lee's Pro 1000 and Load-Master progressive presses, this universal-fit measure handles high-volume reloading with a smooth, reliable operation that's tough to beat. Whether you're processing hundreds of rounds for the range or keeping your hunting loads consistent, the Pro Auto-Disk system delivers the convenience and repeatability you need for mass production reloading.
The teflon-coated metal casting and elastomer wiper combination create a powder measure that operates smoothly while virtually eliminating leakage—a real advantage when you're running a press for hours. The design won't cut powder, preserving the integrity of your charges. A large hopper with a shut-off valve attaches via brass thumb nuts, making disk changes quick and straightforward. The positive pull-back lever adds another layer of safety to your reloading routine, giving you confident control over each charge drop.
This measure comes loaded with four interchangeable disks covering a wide range of charge weights, from light pistol loads to full rifle magnum charges. The half-pound hopper capacity means fewer refills during long sessions, keeping your workflow uninterrupted. Whether you use it with a Powder Thru Expanding Die or a Rifle Charging Die, you'll appreciate how the swivel adapter and spring return lever integrate into your setup.
