Lee Loader

I bought a Lee auto drum for a 223 load using Tac powder and have been getting up to 4 tenths of variance and 2 tenths regularly. Any have this issue? Any help?

Have you washed the drums and container with a detergent such as Dawn? Let it air dry. I dust the drums with mica or graphite when I change them out. I use a small brush to dust up into the adjustable chamber. As the basis for any Lee powder delivery system used over the years, I found that the drum's tension nut was not large enough for my hands to apply consistent pressure. Aftermarket 3D printed knobs corrected that.
