STATION No. 6 Final Crimp.
This station puts the “lead” or radius on your shells
for easy feeding, especially in auto loaders and pumps.
This can be lowered or raised to get the desired “lead.”
It is important not to have this station adjusted too deep
or you will crush the shell just above the brass. This
is very critical with paper shells, and straight wall cases.
Cannot Index the Turret.
Station No. 1 or No. 2 can cause the problem. In Station
No. 1, it would be caused by the machine not going to
the top of its stroke with the shell remaining part way
in the resize collet preventing the carrier from indexing.
Another cause can be the primer not being fully in¬
serted. If you can see that Station No. 1 is not causing
the problem, remove the primer seating assembly
described earlier, drop the shell out the bottom and look
if the primer is fully seated. If not, the problem is usually
caused by foreign material (powder) in the primer seat
assembly, or the tube not being adjusted low enough
to push the primer all the way in. At times, oversize
primers can cause the problem, but this can almost
always be overcome by lowering the tube a little.
Using Large Lead Shot
Our charge bars with the soft insert allow you to reload
with virtually any shot size up to BB. To prevent the lodg¬
ing of large lead shot in the rammertube, we recommend
the use of our steel shot, large lead shot Adaptor Kit No.
8581-12. This is available in 12 ga. ONLY.
Charge Bar Will Not Release
and Drop Shot or Powder.
This is almost always caused by the reprime tube not be¬
ing adjusted deep enough. It is necessary forthe Clamp
No. 507, Photo No. 35, to raise off the turret about 3 / 16 of
an inch. Refer to adjustment for Station 2, page 11.
Another cause can be the measure not being tipped
all the way down. Pull the measure down solidly and
make sure the pivot screw is tight enough to keep it
there.
Charge Bar will not lock without shell in Station No.
2 (keeps charging shot and powder with no shells in
the machine).
Check to see that the bar stop Screw No. 303, Photo
No. 2, is touching the left side of the slot, that it travels
in with the handle down. If not, check for a bent return
Bracket No. 670C. It can usually be adjusted for by
turning Nut No. 304J, Photo No. 44, to shorten the rod.
Check the spring and Bar Lock No. 670A, Photo No.
15. When pushing the bar to the left, the spring should
snap the lock up and keep the bar from moving to the
right.
Inaccurate Powder or Shot Charges.
Almost always caused by short travel of the charge bar.
With a full carrier when the handle is depressed; the
bar stop screw must travel to the full left side of the slot.
If it fails to; turn adjustment nut up on automatic charge
rod, Photo No. 44, so that the screw just hits the left
side of slot when handle reaches bottom of stroke.
Note: It is always recommended that powder and shot
charges be checked with a reliable scale. When check¬
ing these charges, do it during the normal operation
of the machine.
Primers do not drop into the primer seat assembly
when the carrier is indexed.
Photo No. 45
The most common cause for this is losing the Index Ball
No. 515D, Photo No. 45. A bent spring can also cause
the problem, Photo No. 45.
Photo No. 46
It is important that you feel a crisp index each time the
ball drops into an indent. This is adjustable. To adjust,
merely turn the Column Spring No. 612, Photo No. 46.
Getting the free end of the spring right at the index ball
gives the highest pressure, Photo No. 46. The maximum
pressure is usually too much for good indexing and
primer dropping. Having the free end of the spring
about 90° from the index ball is usually about correct.
