Primer Bar Sticking
Quote from Reloader on February 12, 2009, 3:27 amIn the last couple of weeks my primer bar has begun to stick in the retracted position. I have removed the primer magazine and cleaned the bar and press removing any debris/primer residue. I have noticed that as you move the press through it's normal stroke the plunger rotates slightly causing the rod which activates the primer bar to push the primer bar to the side instead of directly in and out. If I hold pressure on happly lateral pressure to the handle as it is pressed through the stroke the primer bar does not stick. the primer bar does appear to have more slop than I remember. Is the rotation in the plunger normal.

The operating rod should freely pivot in the bracket clamped to the primer shield. If it doesn't, then clean the end of this rod, lightly grease it, so that that it moves freely in the bracket.
Another possibility is that the primer cup & punch aren't fully seated in the primer slide. Remove the primer feed from the machine, and lift off the primer slide. Using calipers, measure from the underside of the primer slide to the top of the primer cup. It should be 1.215-1.220" tall. If too tall, use a clamp or vise to reseat them.

I finally decided to get some fine sandpaper and sand the area that the plunger was making contact with. After sanding and trying it for about 15 minutes the plunger no longer contacts the primer tube and now works flawlesly. Sounds like you guys at dillion need to take notice of this problem.

Then I realized that cleaning alone did'nt fix it so I did some research and found out that a little lubrication did wonders! Not just any ole lube though. Use some extra fine, dry powder Graphite Lube on the primer bar, black plate and the rod and load away. I haven't had any more primer problems (sticking bar) in over 2000 rounds of 9, 40 and 45 cal.
