Discovered my wet tumbled brass for 9mm has the powder funnel/expander "sticking" and the bullet seating more difficult vr. dry vibrated brass from corn cob media. I figured out the dry corn cob is leaving a dust film on the brass that acts as a lube. The wet tumbled is squeaky clean so it sticks. Each stroke of the handle I have to "pop" it upward (not hard just a bit) to unstick the expander and down stroke is firmer as the bullet is seated. Anyone using a little case lube even on pistol brass to help with the processing consistency? Set up: Progressive Dillon 1050 running 9mm. Not automated yet. I have seen with the AmmoBots they say to lube all cases. Thinking that might be what I am missing with it even just hand operated.
