and pump the operating handle. The primer will be
pushed out and dropped into the spent primer cup
(#13651). Continue to pump the handle and observe the
advancement of the cartridge from station to station until
it is ejected into the cartridge collection box. Now take a
new primer and drop it (shiny side down) into the primer
magazine (#13673). Operate the handle and the primer
will appear at Station 2, press forward on the handle, pick
up the primer with your fingers and put it back into the
primer magazine. The forward pressure on the handle is
important as it exerts the pressure necessary to seat the
primer in a cartridge.
Reinsert the case in Station 1, drop the primer in the
primer magazine and operate the handle. As the case is
moved to Station 2 press forward firmly but gently and
you will feel the primer being seated. Cycle the machine
and eject the primed round.
IMPORTANT: Let’s do it again but this time do not put
the primer in the magazine. Repeat the sequence using an
unprimed case. Notice how the primer punch tends to
stick in the cartridge when no primer is present. This is the
feeling you get when your Square Deal “B” runs out of
primers.
Now that you’ve seen the Square Deal “B” function,
read the following description of what is happening at
each station.
Understanding the Machine
Station 1: When a cartridge is fired, it expands. The
carbide resizer returns it to factory dimensions. The
primer decap pin knocks out the old primer and deposits
it into the spent primer cup.
No adjustments are ever necessary at this station.
Station 2: As you recall, when you press forward on
the handle you will seat the primer, but that’s not all that’s
happening here. As the cartridge goes up into the powder
measure it encounters a powder funnel that slightly
“bells” the mouth of the cartridge – this bell or flare
enables you to start your bullet easier at Station 3. As the
powder funnel is carried upward by the cartridge it will
operate your automatic powder measure and dispense the
amount of powder chosen.
Two adjustments are possible here. The amount of bell
has been adjusted at the factory; however, you may
increase or decrease the amount of bell by simply
screwing the powder die into or out of the toolhead. (See
Fig. 13.)
The second adjustment is the most important of the
entire loading sequence and must be approached with a
great deal of caution. You must adjust your powder
measure to meter the proper weight of powder in grains
for the load you’ve selected from a powder manufacturer’s
chart or reloading manual.
Cycle your empty cartridge into Station 2. Turning the
adjusting screw as shown on Fig. 14 will open or close
the powder insert. Fill the powder measure with the
powder of your choice. Cycle your primed practice round
into Station 2 to activate the powder measure. Do this
several times and then, using a powder scale, weigh your
charge. (See Fig. 15.) Then, by trial and error, continue
adjusting until the proper weight of powder is achieved.
Run it six more times just to be sure.
With the powder measure up and running let’s get
some primers.
