Just like evan, I find that it cuts some granules. That annoys me, but it isn't the end of the world. 3031 is one of the most difficult. Along with 4831, 4350 and the 4064 evan mentioned. In fact, 4895 granules look small compared to those chunks of powder. I do get a little extra variance in the Pro Auto Disk with the four large grained powders I mentioned, which bugs me if I'm trying to work up a special load but doesn't bug me for practice range ammo.
I truly prefer the rotating drum powder measure for large grained powder. That would be your Perfect Powder Measure for Lee presses, or the equivalent from all the other manufacturers.
