Dillon Precision RL 550B Instruction Manual

							Station One
In the first station, Fig. 16, brass is resized,
deprimed, and then reprimed. 
Using the die lock rings provided, screw the sizing
die into the toolhead. Raise the platform and screw the
die down until it touches the shellplate. Then back it
off one-half turn. Lower the platform and insert an
empty case into Station One and cycle the operating
handle. Now check it for sizing and depriming.
If it looks good, raise the platform so the case is in
the die, tighten the lock ring on the die and tighten the
decapping stem. This will keep everything centered. 
A note of caution, never attempt to deprime a live
primer. An explosion may result.
Station Two
In the second station, the powder is dropped and
the mouth of the case is belled. This is where the
Automatic Powder System is installed.First, screw the powder die (#20064) into the
toolhead, Fig. 17. Now insert the pistol powder funnel
(*#13782) or a rifle powder funnel (*#13426) with the
tapered end down, Fig. 18. The funnel should move
freely in the die. 
Set the powder measure assembly onto the powder
die, Fig. 19. The powder measure clamp (#13939)
should fit loosely around the die, tighten the screws
just a little. This will enable you make adjustments to
the die easily, Fig. 19. 
Fig. 16  - A fully loaded shellplate, directly below the
proper dies. Clockwise from Station One, the cartridge at
this station is resized, deprimed and reprimed. Notice the
cartridge retaining spring holding the case in place.
Station Two bells the case mouth (pistol only) and
dispenses the powder. Station Three seats the bullet.
Station Four crimps the bullet.
Fig. 17 - This photo shows the powder die in its correct
position (Station Two) in the toolhead. The powder die
may be higher or lower depending on the caliber it is being
adjusted for
.
Fig. 18  - Drop the powder funnel into the powder die
tapered end first. The funnel should move freely in the die.
Fig. 19  - The powder die can be easily adjusted by turning
the die beneath the toolhead while holding the powder
measure securely from above.
11* Indicates a caliber specific part. See the caliber conversion
chart on page 16 for the caliber you are loading for. 
						

							On rifle cases, the die should be adjusted so that the
powder funnel will contact the mouth of the case and
then fully actuate the powder bar, Fig. 20 & 21. These
adjustments are accomplished with a case in the
shellplate and alternately raising and lowering the
operating handle, while adjusting the powder die, Fig.
19. When properly adjusted, the powder bar will be
moved to its full rearward position by the case, Fig. 20
& 21. When you have determined that your
adjustments are correct, tighten the lock ring and the
locking collar. 
Next, attach the powder measure fail safe rod
assembly to the bellcrank (#17839). 
Using your thumb
and index finger of your right hand, move the lock-
link down to align the hole with the slot on the
Powder Measure bellcrank (#17839). Then insert the
rod (#97000) through the two holes, Fig. 20. Next,
lower the operating handle (#20636). Insert the powdermeasure rod into the slot in the return bracket (#13885)
press the shoulder washer into the slot from the
bottom. Move the operating handle to the priming
position, press the operating handle firmly forward.
Tighten the blue wingnut (#13799) until the top of the
spring (#14033) just touches the underside of the
return bracket (#13885). We’ll come back to filling the
measure with powder and adjusting the bar. The
purpose of the powder measure failsafe rod (#97000) is
to return the powder bar to its closed position.
Station Three
In this station the bullet is seated to its proper
depth. You need to refer to a loading manual for
overall length of the completed round. 
Put a case into the shellplate at Station Three. Raise
the platform up and screw the die down until it just
touches the shellplate and back it out two turns. Now,
back your seating stem out.
Place a bullet on the case and operate the handle.
Using a dial caliper or case gage, check for overall
length. Keep screwing the seating stem down in small
increments until the correct overall length is achieved.
Once you are satisfied with the overall length, tighten
the lock ring.
Station Four
The crimping operation is performed at this station.
Insert the crimp die and place an empty case in
Station Four. Raise the platform and screw the
crimping die down until it touches the rim of the case.
Now lower the platform and screw the die down an
additional one-quarter of a turn. Place a round in
Station Four with a seated bullet and cycle the
operating handle. 
You will need to refer to a loading manual to get
proper crimp dimensions for the caliber you are
loading. A dial caliper is required to take accurate
measurements from your crimped round.
If more crimp is needed, screw the crimp die down
in small increments until you get the desired crimp,
now tighten the lock ring.

							Adjusting the Powder Charge  
You will notice an adjusting bolt on the back of the
powder bar, Fig. 22.. Turning the bolt counter-
clockwise reduces your powder charge, clockwise
increases the charge. Your machine comes with two
powder bars – one large and one small. 
Rule of thumb: Use the large bar whenever
possible. These bars are easily changed, Fig. 23. Use a
reloading manual to determine how much powder
you need for a particular load and an accurate
powder scale to determine the weight. A high qualityprecision powder scale is available from Dillon. You
should now fill the powder measure with your
chosen powder. Place an empty case under the
measure and operate the machine's handle. Then, by
trial and error adjustments, determine the correct
weight of your powder charge. You are now ready to
fill the primer magazine.
Primer Early Warning System Installation 
(See item #20302 on page five for assistance.)
Remove the follower rod (#13707) from the
assembly bag and set it aside. Install the battery and
the battery cover (#13857) in the system’s main body.
Slide the Early Warning System assembly down over
the knurled cap on your primer magazine (#13957) and
lightly tighten the clamp screw.
Primer Magazine
You will notice that the primer magazines and
primer pick-up tubes have different colored tips.
They have been color coded to help you identify
size more easily. 
The color code is as follows:
Blue Small Primer Magazine Orifice
Red Large Primer Magazine Orifice
Yellow Small Primer Pick-up Tube
Green Large Primer Pick-up Tube
Select the proper size pick-up tube and fill it by
placing the plastic expandable tip over loose primers
and pressing down. The shiny sides of the primers
need to be facing up, Fig. 24.
This is most easily accomplished by using a primer
flip tray, which will arrange them all for you, Fig. 24. A
quality cast metal flip tray is available from Dillon and
is a better choice than the smaller plastic trays which
are difficult to use and have a tendency to warp. 
* Indicates a caliber specific part. See the caliber conversion
chart on page 16 for the caliber you are loading for.

Primer flip tray.
Fig. 22  - Turning the bolt counter- clockwise reduces
your powder charge, clockwise increases the charge.
Fig. 23  - After emptying the powder measure,loosen the
bellcrank screw (#13904) sufficiently to allow you to
remove the powder bar. Insert the new powder bar and
reverse this procedure.

							Once you’ve filled the pick-up tube, make sure the
little retaining clip is in place at the top of the tube.
Pivot the switch lever (#13864) away from the Early
Warning System housing. Invert the pick-up tube over
the knurled cap (#13957) of the primer magazine, Fig.
25. You will notice the cap has a bevel to help you
funnel the primers in. Hold the tube in place, pull the
retaining clip and allow the primers to drop into the
magazine. Pivot the switch lever back over the Early
Warning System housing. Gently slide the follower rod
down into the primer magazine tube until the follower
rod touches the primers. 
When you are nearly out of primers (about three
left) the follower rod (#13707) will activate the buzzer. 
A word of caution: primers are easily detonated,
sometimes by a remarkably light blow. Treat them as if
they are as fragile as eggs. Never force them.
At Last
If you’ve followed instructions, you are now ready
to load. 
Many reloaders develop their own style when
using the RL 550B. But, let me explain the most
efficient method. Try it and later, if you want to make
changes in your technique, go ahead. 
Place your bullets in a box to the left of the RL 550B
and the empty cases in a box to the right. A few extra
cartridge collection bins (#13839) are ideal for this. 
You will notice an adjustable retaining spring at
Station One. This spring should be adjusted to almost
contact the case when it’s placed in the shellplate. 
Now, with your right hand, place a case in Station
One and smoothly pull the operating handle. This
resizes and decaps this case, at the same time your
primer slide should be automatically carried back tothe primer magazine, where it will pick up a primer.
Now, raise the handle smoothly. The primer slide
(#13920) will come forward with a primer and place it
under the deprimed case. If you are using the handle
gently, you will feel the primer contact the primer
pocket. Press forward firmly until the handle stops.
Your primer will now be seated. 
Advance the case to the second Station by pressing
on the index sprocket (#13720) with your left thumb.
Place another empty case into Station One and pull the
operating handle. Station One will repeat as before.
Station number two will bell the case mouth and
dispense the powder. Again, raise the handle, index
with your thumb and place a bullet on the powder
charged case at Station Three with your left hand, Fig.
7. With your right hand, install a new case at Station
One and pull the handle. Stations one and two will
repeat as before.
Station Three will seat the bullet. Index with your
left thumb and put in a bullet. Put an empty case into
Station One with your right and operate the handle.
Stations one, two and three will repeat: Station Four
will have crimped the bullet. Index again and your first
completed round will tumble into the cartridge
collection bin. Now just add a bullet and a case. Each
time you operate the handle you’ll get a loaded round.
Works good, right? If not, go back over the procedure. 
If it’s not right you need to do some...
Trouble Shooting
Use 30 weight motor oil on the main shaft and
bearing grease on the pivot pins. Do not use spray type
penetrating lube such as WD40 or Break Free as you
run the risk of contaminating powder and primers.
Problem One. Primers are not seated deeply
enough.
A. Shellplate too loose.
B. Shellplate upside down. You should be able to
see a stamped shellplate number facing up.
C. The crimp in the primer pockets of military brass
will cause this problem. Crimps can be easily removed
by use of a Dillon Primer Pocket Swage.
Problem Two. Erratic powder bar operation: 
A. Turn the powder die (#20064) clockwise in one-
eighth turn increments. This will insure complete
powder bar activation. 
B. Extruded pencil type powders will not flow
smoothly through smaller sized powder funnels
because of their length. Another problem with
extruded powders is getting them into small necked
cases. Many times these powders will “bridge” across
the case mouth and cause spillage and erratic charges,
There is no fast way of dispensing these powders and
if you insist on using them in small mouthed cases it
is best to weigh every charge by hand. Modern ball
type powders will do for most reloading situations.
These powders will do everything the pencil powders
* Indicates a caliber specific part. See the caliber conversion
chart on page 16 for the caliber you are loading for.14
Fig. 25  - Drop the primers into the primer magazine. 
						

							15
will do, but without this problem. Warning: Do not
use I.M.R. pencil lead type powder in cases smaller
than .30 caliber.
Problem 3. Primer jams or misfeeds. 
A. Primer misfeeds can be caused by
misadjustment of the set screw (#13961) in the primer
feed block, Fig. 12.
B. The most common cause of primer misfeeds or
jams is the primer punch not seated fully into the
primer slide. This will cause the primer seating cup to
strike the flexible orifice on the bottom of the primer
magazine tube.
Warning: If the primers are jammed and will not
feed from the bottom of the primer magazine, Do Not
Attempt to force the primers or the primer slide. An
explosion resulting in injury may occur.
C. Another common problem is that the primer
slide fails to return fully forward with the new primer.
Periodically wipe the primer slide with rubbing
alcohol. This removes the spent primer residue that
causes the slide to drag.
Problem 4. Crushing cases: 
A. If your dies do not have a radiused lead-in you
must guide the cases into the die. The best solution is
to replace the offending dies with dies having the
proper radius. 
B. Always tighten your die lock rings with a case in
the die. This will assure you of proper alignment
between the die and the shellplate. Adjust your
depriming stem in the same manner and it will always
be on center.
REMEMBER
Be sure to use the necessary precautions when
loading lead bullets or when casting lead bullets.
Exposure to lead can cause cancer, birth defects, and
reproductive problems. Be sure to wash your hands
thoroughly after handling lead. When firing lead
bullets, be sure that you have adequate ventilation.
Keep any lead items out of reach of children.
Press forward firmly on the handle once it is at the
aft position to seat your primers fully. 
Watch the powder bar function to make sure you’re
getting powder. 
Set the bullet straight on the case at Station Three so
that it enters the die correctly. 
Watch your supply of powder, you’ll be using it
faster than you think you are. 
Take your time and learn the machine and its
function. The RL 550B will deliver hundreds of trouble
free rounds in short order, just relax and take your
time in the beginning. 
Keep it clean – primer residue, spilled powder and
just plain dirt can jam your machine. 
Clean your powder bar about every 500 rounds.Some powders build up and will eventually stick the
powder bar. Paint thinner, acetone or lacquer thinner
works well to remove any build up.
