I still have the Lee PPM that came with my old Challenger kit..I was never satisified with it even with ball.It would throw fairly consistant weights with ball,but the measure had to be close to full at all times,and with stick it would crunch,and break powder so bad that the handle could not even be cycled smoothly enough to even dream of consistancy.I have yet to see a conventional powder measure that I really trust to be truly consistant .
