15. Wads crush hull mouths upon insertion:
Check Wad Guide for missing wad fingers. Replace if
fingers are missing.
Check alignment of Wad Carrier Arm. At the insertion
position, the Wad Guide should be centered to slightly
forward of center in relationship to the Wad Starter Rod
above it. See
# 5 (page 8) of Component Adjustment section.
16. Inconsistent shot charges:
Index Shaft and Brackets may be worn or loose causing
the Charge Bar to not make complete left and right
movements.
The Shot bushings were calibrated to soft lead shot.
Chilled or Magnum shot has a higher antimony content
and though the shot size may be
# 8 or # 7.5 etc., there is
less mass for the same volume versus soft lead. Bushings
may be enlarged to drop a larger volume of shot or
sleeved to reduce the volume of shot.
17. Hulls collapse at Station 7 – crimp:
Wads are not seated deeply enough causing the shot
column to be too high. The crimp die cannot push the
crimp closed over the shot column, exerts excessive force
and collapses the side of the hull.
Too much crimp pressure, reduce crimp spring force.

right wrong
May be sporadic due to a damaged Case Holder, only
affects one of the eight case holder stations. If multiple
Case Holders are damaged, it will happen more frequently.
Damaged Case Holder(s) need to be replaced.
20. Hard ejection of loaded round at Station 8:
Typically caused by a damaged case holder. The Case
Holder does not retract causing extra force to be used to
eject round. If multiple Case Holders are damaged, it will
happen more frequently. Damaged Case Holder(s) need to
be replaced. Remove hulls from press. Using a
5 /
16
" hex
wrench, loosen socket head cap screw inside of Case
Eject Rod Holder
(photo 52) and remove from press
(CAUTION: Note position of Case Eject Rod, if it is not
positioned properly upon reattachment, damage may
occur). Remove Case Holder Plate Assembly by lifting
counter clockwise from Shell Plate Holder. Remove eight
8-32 button head cap screws with provided
3 /
32
" wrench. Lift
off top plate, replace damaged Case Holders and
reassemble. Insure all Case Holders retract freely before
tightening the screws. Reinstall onto press ensuring Case
Eject Rod is in the correct position
(photo 53).
18. Hull sticks up into Crimp Die at Station 7:
Crimp Die is adjusted down too far and/or Crimp Spring
force is excessive. Reduce spring pressure by backing off
nut above spring
(See photo 42). Also, if the wad is not
seated deeply enough (Station 5), the shot column is too
high, not allowing for proper crimp.
Case Holders may be damaged and must be replaced.
19. Hull sticks up into Taper Crimp Die at Station 8:
Excessive taper crimp being applied-loosen top lock nut
and raise die.
Or as above, improper wad depth, causing too high of a
shot column.

21. Case Eject Rod broken:
As above, the extra force necessary to eject the loaded
round with damaged case holders puts extra force on the
Case Eject Rod, causing it to break. Also, after removing
and cleaning under the Case Holder Assembly, the Case
Eject Holder was aligned improperly under a die station,
when the handle is cycled, the die breaks off the eject rod.
22. Powder or shot is dropped without a hull present:
Shut Off is stuck to the rear. Shut Offs, Charge Bar and
housing may need to be cleaned. Powder dust residue
may cause the Shut Off to bind. Also, If your shot is very
dusty, this also causes the Shut Off to bind.
DO NOT USE
RECLAIMED SHOT!
