Mr. Whit, any other measure...
The Auto Disk measure is the ONLY Lee product I will no longer use. Everything else works as advertised and pretty well.
Supposedly, the AutoDisk works well with IMR type powders. I could never get good results with any kind of power: stick, ball, spherical, flake - anything.
I have used an old Lyman #55 measure, several Dillons (I use an XL 650 press these days), a Frankfort Arsenal measure, an old Bending & Mull and a Pacific Pistol measure. (And Lee dippers.) Unique worked fine (no serious velocity excursions) with all of them - except for the Auto Disk.
I've been reloading since 1970 or so.
