Lee Precision Auto Disk Powder Measure

The Lee Precision Auto-Disk Powder Measure automatically dispenses charges more uniformly than any other powder measure. This powder measure is best used for charging handgun cases with a Lee Precision Powder Through Expanding Die. The case itself actuates the measure as the neck is being flared during the presses maximum mechanical advantage. This assures the smooth, even action of the measure. A built-in baffle, and precisely molded, glass reinforced charge disks contribute to the unmatched charge uniformity. All four disks are inlcuded with the Auto-Disk Powder Measure.

If you want to use the Auto-Disk Powder Measure to charge powder on a Lee Precision Classic Turret Press, you will also need to order a Lee Precision Auto Disk Riser which is sold separately. The riser raises the Auto Disk powder measure higher above the mounting location on the Turret Press to provide clearance for use of the Lee Precision Safety Prime Feed Large and Small.

  • Author: Pico (Rick) Cianflone
    I have this powder measure since 1994, changing the discs a bit of a pain, but it throws accurate charges.
  • Author: John Morgan
    This is a great measurer, but the adjustable charge bar is a must, it makes adjustments quick and easy. I use alot of blue dot and 800x, it throws them very consistant. don't forget a riser when ordering this, it's required for use on the classic turret press. I'll be purchasing the swivel conect very soon also.
