I am currently trying to get my new RCBS Pro 2000 progressive press set up. The problem I coming across is the freaking powder measure. I CANNOT get it to throw consistant charges. I'll get the desired weight (in this case 6.4 gr of Unique) and then when I try to do my 10 test charges, it freakin starts throwing heavy after 4 - 5 charges. This measure does NOT have a freaking set screw which REALLY surprises me. Any help or suggestion would be MUCH appreciated.
