Reloaders, this Lee Auto-Drum is a game-changer for speeding up your process while keeping things accurate. It's a case-activated powder measure, meaning it automatically drops your powder charge when you insert a cartridge case into your press – no spilling, no double-charging, just smooth, consistent throws. It comes with two interchangeable, infinitely adjustable drums that let you dial in any charge weight from about 1 grain all the way up to 80 grains, covering a huge range of cartridges. The clever elastomer wiper inside is the secret sauce – it prevents powder from getting sheared (crushed), which is especially great for tricky extruded stick powders that other measures struggle with. The body is machined with a labyrinth groove that mates perfectly with the nylon drums, creating a leak-proof seal even with fine powders. It has a quick-change hopper with an on/off valve so you can swap powders fast. If you're tired of manually weighing every charge or dealing with a messy, inconsistent measure, the Auto-Drum brings automation and reliability to your bench without breaking the bank. It's a must-have for anyone running a progressive press or just wanting faster, more consistent reloads.
