Lee Precision 90453 Quick Change Drum Set Black Nylon Works With Classic/Auto Drum Powder Measure

The Lee Precision Quick Change Drum Set gives handloaders a versatile solution for precise powder charging across caliber ranges. This four-drum system works seamlessly with both Lee's Classic Powder Measure and Auto Drum Powder Measure, letting you swap drums in seconds without tools or hassle. Whether you're loading lightweight rimfire or heavy magnum rifle rounds, having the right drum on hand eliminates setup time and keeps your reloading session flowing.

Two small drums handle the lighter end—from 25 ACP up through 223 Remington—while the pair of large drums covers everything from 223 Remington through the big magnum cases. An included insert lets you reduce a drum's capacity when you need smaller charges, giving you even more flexibility without buying additional equipment. Every drum is infinitely adjustable within its range, so you're not locked into preset increments; dial in exactly what you need for your load.

Fine adjustment is straightforward: each full turn of the adjusting screw equals 0.1cc (roughly 1 grain of powder), and every drum ships with a graduated adjustment key marked in 0.01cc increments for precise 1/10-grain tweaks. Once you've dialed in a load, mark the drum's flat surface with your charge weight and powder type—a simple habit that saves time when you come back to that caliber next season. No learning curve, no guesswork, just repeatable powder drops every single time.
