Bullet feeder action arm doesn't move the bullet feeder lever

Check to make sure that you have good tension on the action rod with the damper. The damper should offer good resistance of movement on the 
action rod to properly cycle the bullet feeder. If you don't have good resistance, you should order a new damper.

Also, move the press handle with authority to operate the bullet feeder. The feeder will not work well if you move the handle slowly in an 
attempt to watch the bullet feeder operation.
