Description
Lee's Deluxe Auto-Drum Powder Measure takes the guesswork out of charging cases on a progressive or turret press. It's an automatic, case-actuated unit, meaning the case itself trips the drum as it rises into the charging die, so you get a measured drop every stroke and no powder spilled when you skip a station. Reloaders who've run it on everything from Lee Classic Turrets to Redding and Dillon presses consistently praise how smooth and repeatable the throws are, often within a tenth of a grain across a string of ten.
What Sets the Deluxe Auto-Drum Apart
The secret is in the drum itself. Instead of the fixed disk holes you find on older Lee measures, the Auto-Drum uses a large, slanted cavity that adjusts by depth, which cuts down on powder bridging and gives you infinite adjustment rather than preset steps. The machined body has a labyrinth groove that mates to the precision molded nylon drum for a leak-free fit, and an exclusive elastomer wiper shears less powder, so it handles tricky extruded stick powders better than most volume measures in this class.
Range and Versatility of the Lee Auto-Drum
Two infinitely adjustable Quick-Change drums come in the box, covering charges from 1 all the way up to 80 grains. That range makes it a genuine do-it-all measure, handling light pistol loads in the low 3-grain neighborhood and stretching up to large rifle cases like .30-06, .308, and 25-06. A lot of folks buy extra drums, preset them to a favorite charge, and swap them in seconds, which is a slick way to run multiple calibers without re-dialing every time.
Handy Touches on the Deluxe Auto-Drum
This version adds a red anodized swivel adapter that gives you a bigger gripping area for threading it into your press and raises the measure to clear the tallest dies, so you can skip a separate riser. The quick-change hopper has an on/off valve for fast powder changes, and all the gears, springs, and levers tuck neatly inside the die-cast housing. It's built in the USA and backed by Lee's lifetime guarantee.

Frequently Asked Questions
What charge range does the Lee Deluxe Auto-Drum cover?
It drops charges from 1 to 80 grains using the two included Quick-Change drums. That spread covers light pistol loads all the way up to most large rifle cartridges, though the big magnums can run past the 80-grain ceiling. For those you'd use a double throw of half charges.
Do I need extra dies to run the Auto-Drum on my press?
For pistol loading it typically works with your existing powder-through expanding die. For rifle cartridges you'll want Lee's Rifle Charge Die, which is sized for bottleneck cases and lets the measure actuate properly. It mounts on Lee presses and plays nicely with many other brands like Dillon and Redding too.
Does the Deluxe Auto-Drum handle fine and stick powders without leaking?
The machined body uses a labyrinth groove that mates to the nylon drum for a leak-free fit, even with fine ball powders. The elastomer wiper shears less powder, which is why it meters extruded stick powders better than most disk-style measures. Running it through a short settle-in before you check your charges helps it lock in consistently.
What's the difference between this and the standard Auto-Drum?
The Deluxe version adds a red anodized swivel adapter that gives you a larger gripping surface and raises the measure to clear the tallest dies, so you don't need a separate riser. The core measure and its two drums are otherwise the same proven design. It was formerly sold under product number 90811.
