MANDATORY SAFETY PRECAUTIONS—MUST BE READ
1. The Basic Risk of Reloading, and Overall Square Deal Design Usage Safety:
1. DANGER! The reloading of ammunition and the handling of reloading components used in the reloading process is inherently
dangerous. Accidents and mistakes in loading can and do occur, sometimes with disastrous results resulting in, but not limited
to loss of hearing, vision, limbs or life. These accidents can occur with the novice and experienced reloader.
2. Dillon Precision Inc. has designed the Square Deal “B” with user safety in mind, doing everything Dillon Precision Inc. knows to
make the use of the Square Deal “B” as safe as possible.
2. Mandatory Square Deal User Safety Minimum Requirements:
1. Dillon Precision Inc. cannot guarantee the complete safety of the reloader/user of the Square Deal “B”. To minimize the user’s
risk, use common sense when reloading and follow these basic safety rules at a minimum.
2. KNOWLEDGE: Study and learn the basics, processes and specifications used in the reloading of ammunition from reputable
sources and publications by prominent bullet and powder manufacturers such as Sierra, Hornady, Speer, Western Powders and
Alliant Powders; including reloading manuals such as the Lyman Reloading Manual and the Western Powder Reloading Guide.
3. EYE AND EAR PROTECTION: Never operate the Square Deal without eye and ear protection.
4. PAY ATTENTION: Give your full attention to the reloading process. Do not watch television, the internet or converse with
anyone while loading. It is a full-time operation.
5. INTERRUPTIONS: If you are interrupted in any manner, always inspect the cases at every station and know exactly what has
been done to ensure that proper process steps have or have not been completed.
6. SMOKING/IMPAIRMENT: Do not smoke or allow anyone to smoke in the reloading area. Do not allow open flames. Do not
load if you have been drinking alcohol or are impaired in any way.
7. SAFETY: Do not remove any safety device(s) from the reloader or modify the reloader in any way. Keep components and
ammunition out of the reach of children.
8. LEAD--CAUTION! Almost all bullets have a lead component, which may or may not be exposed. Be sure to have proper
ventilation while handling the lead component (bullet) or when shooting. Lead causes birth defects, reproductive harm and
cancer. Wash your hands thoroughly after handling lead components or shooting.
9. POWDERS--DANGER! There are many kinds of powders (propellants) used in the reloading process and are in general specified
as rifle, pistol or shotgun powders. Powder selection is specific to the bullet caliber, weight and type of bullet being reloaded.
There is no way to overstate the care and selection of a powder to be used in the reloading process. Again, refer to
established bullet and powder manufacturers. Using the wrong powder or amount of powder or mixing powders can result in
serious injury or death. Never mix powders. Always store the powder in its original container. Never have more than one
type of powder in the reloading area at one time—preferably store powders in a separate room. Observe all maximum load
warnings.
10. PRIMERS—DANGER! Primers contain a small amount of a shock-sensitive chemical that explodes when struck by a firing pin
or hammer or accidentally crushed. Never force primers. If they get stuck in the operation of the loader, carefully disassemble
the reloader and gently remove the obstruction. Never attempt to clear primers that are stuck in either the primer pickup tube
or the primer magazine tube. Never, under any circumstance, insert any type of rod into these tubes to attempt to push out
stuck primers—PRIMERS CAN “CHAIN DETONATE.” If a primer(s) gets stuck in the magazine or pickup tubes flood the tube
with penetrating oil/WD-40, throw it away and call Dillon for a free replacement. Never attempt to deprime a cartridge case
with a live primer. Depriming a live primer is one of the most dangerous things you can do in reloading and can cause serious
injury or death. Never attempt to further seat primers on a loaded cartridge. Use only the primer for the specific application
for which you are loading.
11. BLACK POWDER--DANGER! Do not use black powder or black powder substitutes in any Dillon Powder Measure. Doing so can
result in severe injury or death.
12. LOAD AND LOADED LENGTH—WARNING! Use only recommended load specifications from manuals and information supplied
by established, known component manufacturers. Avoid maximum loads listed in loading manuals. Be extremely careful to
avoid a double charge. Dillon has no control over the components and specifications used when reloading with the Dillon
equipment. No responsibility is implied or assumed for results obtained through the use of or inability to use any such
components or reloading specifications.
13. QUALITY CHECKS--At a minimum, perform periodic quality checks every 50-100 reloads-ESPECIALLY the powder charge.
14. PROPERLY LABEL RELOADED AMMUNITION: Label the reloaded cartridge with the overall length, bullet manufacturer, type
and weight-- primer manufacturer and type--powder manufacturer, type and powder charge and date loaded.
15. RELOADING AREA-- The reloading area should be well lit, dry and comfortable without breezes.
16. BE PATIENT and OBSERVANT— Users should have no trouble achieving published loading rates that are conservative. Be
smooth and steady. The reloading process is not a process to hurry--- If something does not LOOK RIGHT, SOUND RIGHT, OR
FEEL RIGHT —STOP, LOOK and THINK! If the problem is not obvious—CALL Dillon Technical Support [phone] or visit the
troubleshooting section at www.dillonprecision.com.

5.4 The Square Deal “B” can be mounted directly to your bench (If you are using the Dillon Strong Mount
proceed to 5.4.4 below). The preferred method of operating the Square Deal “B” is standing up. This
gives you the leverage for the force needed to properly seat primers.
5.4.1 For mounting directly to a bench, bring the Square Deal “B” to the forward edge of your bench as shown
below. The Square Deal “B” requires ¾” clearance under the front edge of the bench. See below.
5.4.2 Mark the three mounting holes using the Square Deal “B” as a template. Remove the machine and drill
three 9/32” holes through the bench. Bolt the Square Deal “B” securely to the bench with ¼” Grade 5
hardware or available Dillon Mounting Hardware Kit P/N14355. Use small diameter washers on the top
and large diameter washers on the bottom, especially if using a wooden bench.
5.4.3 Slide the Spent Primer Cup into the mounting slots on the Bracket.
.
5.4.4 There are three other optional methods for mounting the Square Deal “B” to your bench.
•The first option is to use the available Billet Dillon Mounting Plate PN62005 by fastening the Plate to
your bench and then mounting the Square Deal “B” to the Plate and as shown below:

17
8.3. Station 1—Sizing and Depriming
8.3.1 There is no adjustment required for Station 1--The Size Die with its Carbide insert drops into Station 1 and is
secured by the Toolhead. The Depriming Assembly threads flush into the Toolhead. The Deprime and Size
Components are shown below. The case is sized and Deprimed in Station #1 on the downstroke of the
Operating Handle.(Note—a Primer is picked up by the Primer Slide in Station #2 during the downstroke of the
Operating Handle during the Sizing/Depriming Operation in Station #1).
8.4 Station 2a--Primer Feeding, Seating, Case Belling and Powder Dispensing--The First Operation of Station 2 is
(a) to seat a primer on the full push stroke of the Operating Handle. The Second Operation of Station 2 is to
(b) expand the case mouth and dispense powder on the downstroke of the Operating Handle.
8.4.1 The Square Deal “B” incorporates an Automatic Linear Primer Feed System utilizing standard Large or Small
Primer Magazine Tubes and interchangeable Large and Small Primer Slides. The Square Deal “B” comes with
the primer size specific to the cartridge ordered. The alternate size Primer Slide is shipped separately. A Large
Powder Bar for the Powder Measure is also included. These components are in the “Tube Pack” --see shipping
contents.
8.4.2 A Primer Early Warning System (EWS)/Low Primer Alarm system is provided. The Primer Follower Rod is the
Actuator for the Primer Early Warning System.
8.4.3 A primer is automatically picked up by the Primer Slide and Primer Cup Assembly from the Primer Magazine.
It is then positioned under the hole in the Shellplate in Station 2 as the case is indexed from Station 1 during the
upstroke of the Operating Handle. The Primer is then seated with a complete push stroke of the Operating
Handle.

8.4.4 The Operation of The Automatic Primer System
•The Square Deal “B” comes set up in the primer size for the cartridge ordered.The alternate size
Primer Slide Assembly ships separately.
•Primers are seated by pushing the Operating Handle fully to the rear, from the Operating Handle’s
“at rest position” at the top of the Square Deal’s stroke.
•CAUTION!
•Learning to feel the correct force to seat a primer is a critical method in the reloading process.
•The Prime will not be seated to the proper depth if the Handle is not pushed firmly and fully to
the rear primer seating position.

•If the primer takes too much force to be seated and the Handle cannot be pushed fully
to the rear—STOP and inspect the case. The primer pocket may be damaged or could
have a crimped primer pocket or the Primer Cup may not be aligned properly with the
Shellplate.
•Low resistance to seating a primer can indicate an enlarged primer pocket that may
not retain the primer. Discard this case.
•Verify that the system feeds primers as follows:
•Remove the plastic Follower Rod and unscrew the Magazine Cap.
•Remove and verify the Magazine Tube is of the correct size/color--The blue tip for
small primers and the red tip for large primers. Note: Any primers left in the
Magazine Tube will fall out in the Magazine Shield Tube.
•Install the Magazine Tube in the Magazine Shield. The tab on the plastic Magazine
Tip, red or blue, must be gently aligned with the slot down in the Primer Feed Body
Housing and then should slide down about a 1/4” more. Tighten the knurled
Magazine Cap just snug.
•With the Operating Handle up in its at-rest position, manually take one primer that
you will be using and drop it anvil side up in the hole in the Magazine Cap as below:
•Cycle the handle smoothly down and back up to the top of the stroke to the “at rest position.”
•The primer should present itself in the Priming Station on top of the Primer Punch as shown below—
repeat this step 3 times--if successful proceed to the next step, if not, proceed to Primer Drop Alignment
Section 10.2.

8.4.5 Verify Primer Seating Depth
•With a primer in the cup as above and the Operating Handle in its up at-rest position, put a de-
primed case in Station 2. Push the Operating Handle fully to the rear seating the primer. Remove
the case and verify the primer is seated flush or slightly below flush.
•The primer seating depth is an important parameter to control when reloading and can be a safety
issue. The ideal seating depth is .002” to .006” (.008” Max) below the case head. WARNING!
