1. Too much Case Lube—clean Size Die and cases and re-lube with less lube.
Case stuck or sticking in Size Die 1. Insufficient Lube on the case.
2. Overpressure or” blown-out” case—out of spec/oversize.

5 Priming Primers not feeding properly. 1. Stuck Primer in the tube. Discard Tube.
2. Damaged magazine tip or tube. Replace tip or discard tube.
3. Debris preventing Primer Slide from traveling far enough into the Primer Feed
body. --Remove and clean Slide and Feed body, or clear with compressed air.
4. Primer Cup on Primer Slide not aligning properly with magazine tip.
Primers may stick on the end of the
Depriming Pin and be “pulled back
up” into the primer pocket
1. In the case of issues with depriming rifle cases, place a de-primed case in Station
one with the Operating Handle in its down position. Adjust the rifle Depriming
Bolt down until it stops on the inside of the cartridge flash hole and then back
the Depriming Bolt up 1 and ½ turns and lock it in place.
2. Polish the end tip of the Depriming Pin, so the taper is gone. This gives a wider
tip, and the primer is less likely to get jammed onto it. Also, you can polish the
end of the tip of the pin so it is less likely to get stuck in the primer anvil.
3. In the case of pistol depriming issues—make sure there are no “burrs” on the
end of the Depriming Pin. Polish if necessary and make sure that the Spring-
Loaded Depriming Assembly is intact especially the “E” clip on top of the
Depriming Bolt Assembly.
The Priming Cup is not picking up
primers reliably under the Primer
Magazine in the Primer Feed
Assembly.
Primers are being caught in
Dispensing Tip
1. Remove the Primer Magazine from the Magazine Shield. Caution! Any primers
left in the Primer Magazine will fall out. Push a small cloth patch, 3/8" x 3/8",
wet with alcohol, through the Magazine Tube several times to clean the interior.
Verify the Dispensing Tip (Red or Blue) is not damaged--Replace if visibly
damaged.
2. To replace the tip, remove the old tip and gently place the new tip on the
aluminum Magazine tube. Make sure it is the correct size/color for the primers
used—Blue for small primers and Red for large primers. Put the Magazine Tube
in the Magazine Shield Tube and orient the tip in the mating slot inside the
primer feed body. Screw the magazine Cap on and use this to push the
magazine tip on the rest of the way—do not over tighten.
Primer Slide is not moving
smoothly back and forth
1. The Primer Track Bearing (14015) is dirty or worn. Clean Track Bearing, both
sides, and the Primer Slide with Alcohol and reinstall using no lube! If worn call
Dillon for a New Slide or Track Bearing.
2. The Primer Operating Rod Bracket is not installed at the proper height or is not
properly aligned with the base. Reposition as shown in 10.3.1.
Primer Slide Punch, Cup and or
Spring are Dirty or have come apart
1. Disassemble Punch (13967), Cup (13824), and spring (14033) by loosening Set
Screw (13996), clean with alcohol, and dry.
2. Re-assemble by fully compressing the Punch, Cup and Spring until they stop
moving and firmly re-tightening the Set Screw (13996)—This requires some
"Fingers"
