Disassemble the priming system and take 600 or 800 grit sandpaper to the sliding surfaces such as the plate & shoe. Also, I took a coat hangar, clipped the straight section out of it, took a piece of masking tape and made a flag out of it on one end. Place it in the empty assembled priming assy after smoothing the ends. Now, you have a low primer indicator that doubles as a weight. It helps for positive feeding of the primers.
Whatever you do, lube the snot out of the ram assy ONCE. Wipe the excess and you're done for probably the life of the press.
