Having issues with my dispenser at a terrible time . It seems to throw charges at .5 to .7 over no matter what. The powder is 4831sc so it shouldn't be an issue. The dispenser was warmed up and calibrated as I always do before I load . It's on the slow setting and with it set for 58 gr I'm consistently getting 58.5 to 58.7 over charges . I've tried to re calibrate it and it doesn't seem to help .
