I have the reddings too, they are not as good as the lee on big stick powder.
That said I would not dream of using LEE for ball or flake powder. That was a big mess...
I found my ancient uniflow back, and since I don't have a measure in Alaska its flying back with me. I swear there were some upgrades to make it better, like a concave measuring chamber and a baffle but a quick google didn't help.. LOL. Its junk, but it beats lee measure spoons all to hell.
