A few months ago I tested charge variance with a few powders in my Lee pro auto disk. Green Dot and the Pro auto disk was a bad combination, especially charges applicable to 380. Pretty significant bridging was the culprit.

I've since switched to the pro auto drum and found that I get less than .2 grain variance with Green Dot. I can now safely use it in .380 to throw a 2.9 grain charge. It is a really nice powder under a 100 grain Xtreme rnfp.
Alliant makes a lot of great pistol powders, and it's easy to overlook Green Dot. Give it a try, especially if you have an auto drum.
