Most powders can be adjusted up or down .1 grain with different combinations of disks. Complete listing of combinations, 4 extra disks, screws and risers are included.

See What One Satisfied Customer Has To Say About The Auto Disk Powder Measure!

Dennis O. from East Peoria, IL:
I just want to say thank you for your fine line of reloading equipment. I usually dont write letters like this but I had to let you know how much I appreciate the reloading tools of Lee Precision. Like so many others I started out with the Lee Precision Loader, but now have moved up to one of your bench mounted presses with Lee Precision dies, Auto-Disk Powder Measure and other Lee Precision tools and accessories. The Auto-Disk Powder Measure is by far the best piece of reloading equipment for reloaders since the invention of the press itself, and now with the introduction of your new neck sizing dies, you've done it again. Several of these dies will be on my reloading bench very shortly. I don't know what new products Lee Precision will introduce in the months and years ahead but its safe to say it will be part of my reloading bench. All this at a very affordable price. Lee Precision, the innovative leader, how true that is. Keep up the good work.
