550 PM slipping
Quote from Reloader on March 21, 2019, 4:50 pmOn a new d550c with 223 setup and verified to be correct I’m having this issue with the powder measure
Position 2 with sized brass
Raise the ram to when the brass touches the funnel
Brass begins raising funnel and belcrank
Bell crank “slips” drops back down
Now it will resume as normal
Once it slips it throws an approximate extra .5 grains
Any thoughts?

My guess is that the case is tipping slightly, and not centered in the powder funnel. Then as the case goes up, the pressure forces the case to center, when the funnel slips down slightly. This jars the powder bar, settling the powder and allowing more powder to fit into the bar.
