See if you can pick up a new or used Lee Perfect Powder dispenser, they work very well with small charges of flake pistol powder.
I bought a Lee kit for the extra press,couldn't stand the scale and sold it,tried the powder measure and didn't give it enough time and went back to my Uniflow,and RCBS 505.
Got into a Lee Classic Turret and wanted to use a dispenser instead of dippers for charging handgun cartridges. So I decided to try the PPM again,mounted it onto the turret on a homemade extension.
Once it is broken in and the tension on the drum is adjusted properly, it drops small charges of Bullseye and Uniquefor 38 Special and Trailboss very accuratetly,plus it meters stick powder without the herky jerky of the drum cutting powder grains.
If you have one that you threw into the junk box pull it out and give it another try, you may be surprised!
