If there's a weakness in the Dillon system, this is it.
Does the primer bar move back and forth smoothly when there are no primers or primer tube in the machine? If not, a heavier (or new) spring may get the primer bar to move, but since it is spring pressure you may end up flinging primers across the room. With springs and actuators disconnected the assembled primer bar should move smoothly through the entire range by hand. If there is a hang up it will have to be re-aligned or smoothed out. My 550 requires a little lube on the contact surfaces to move smoothly.
If the bar moves smoothly empty but hangs up when primers and primer tube are introduced, You may need a new primer tube end. If the primer tube is heavily over tightened it can crush. This may allow it to interfere with the edge of the primer cup on the transfer bar.
Good luck. Don't get discouraged. It will work and can be fixed no matter what is wrong. Just take it one component at a time.
