I had an original disk measure and bought the upgrade to the disk pro. It came with an adjustable charge bar. I put it all together and it didn't work.
Then I put it together right and it seems to work quite well. [smilie=w: I have used 700x, Red Dot, Clays, and Bullseye in it so far.
the hopper has to go on a certain way on the pro version and I had it on backwards...duh!!! :bigsmyl2:
