I have the Lee powder measure. I think it's pretty accurate. The powder can make a difference of course. I was using H335 for my .223 rounds. Everyone said it would meter well, but it's to fine for the Lee disk measuring system. I had powder all ofer the place. Flake and stick powders see to work well. Unique, Bullseye, Benchmark, Universal, Varget all seem to meter pretty consistently.
It's usually +/- 1/2 line on my Lyman scale. I dont have a digital scale. But that's close enough for me. I'm not trying to split the atom or anything.
