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.
