I have a 20 gauge lee load all that a neighbor gave me back in college. It never was fast and sometimes I get a funky crimp if I don't line up the shell right, yet if you have the time, it will do the job.

Only thing I have found when using Herco powder, not much comes out the slide bar area moving it back and forth because it's a flake powder. Yet with WSF, I will have that tiny grain powder over the place after reloading a box of shells.
