There is a prescribed dimension for the height of the primer cup, measured from the bottom of the bar to the top of the cup....I saw it recently, and can't swear to it, but IIRC it it 1.115-1.120. If I can find where I saw that, I will check back in and post it.

The first Dillon I owned was an old 450 (not bought new), and it did not come with two primer bars. It came with one primer bar and two primer rams and cups, which could be swapped out on the bar. The set screw was used to anchor the ram at the correct height--I never knew the dimenion back then; just did it by eye "close enough" method.

I wass recently helping a co-worker who just acquired a 450, and the ram and cup are available individually from Dillon. If you buy those parts and install them, the correct dimension will be very helpful.
