Since were discussing Spolar..I'm having a heck of a time with my primer feed system. As the primer tips from the tray into the slot, quite often the next primer slides in behind it and stops it from falling down the chute. This happens with Winchester primers, I didn't seem to have any problems with the Remington's I used before. I called Spolar but got the answering machine so.....help me out. GaryL.
