Here's some background info that may help you...

• If you intend to work with a single powder with a single load for all guns, then you may prefer a fixed bushing type powder measure. In this style powder measure, the volume of powder being dispensed is permanently set by a replaceable bushing. The advantage is that the charge setting can NEVER come out of adjustment. The disadvantage is that you have to purchase and fit a new bushing in order to change the load.

All the Lee series and the RCBS "Little Dandy" use this type design.

• If you intend to work with multiple powders or with varying loads, then you may prefer a variable cavity type powder measure. In this style powder measure, the volume of powder being dispensed can be changed by a simple manual adjustment. The advantage is that the charge setting is fully variable at no additional cost. The disadvantage is that adjustment can loosen and change during a loading session.

RCBS "Uniflow", Hornady, Lyman, and all the Reddings use this type design.


► With either design powder measure, I'd highly recommend independent mounting so that the measure 1) can be moved to the most comfortable position for loading, 2) then quickly emptied when finished, and 3) then moved out of the way when not needed. Such a setup looks like this...

► Besides the element of added loading speed, a powder measure also increases your safety by allowing you to compare the powder height of all 50 cases in the loading block before the bullets are seated.

Hope this helps. ;)

The Lee Auto-Disk (and Pro) is the only Lee measure that, to my knowledge, using a fixed bushing. The Lee Perfect Powder Measure, Classic Powder Measure, and Auto Drum are all adjustable. And even the Auto-Disk has an available charge bar that's adjustable.

I understand the point of your post, just wanted to clarify that one point.

This is correct, Disk/Pro Disk use disks with fixed size openings. 4 disks with different size openings included. (adjustable charge bar is available)
The PPM and the Auto drum are adjustable. The Auto drum has two rotors small and large, PPM has only one, both are adjustable.

The Pro Disk and Auto Drum mount on a Lee powder thru die which is the same a a normal press die. The case rises on the press thru the die and activates the measure dropping powder in the case.

Otherwise good info in the above post.
