Dillon Precision RL 550B - Manual (Page 13)

Adjusting the Powder Charge
You will notice an adjusting bolt on the back of the
powder bar, Fig. 23. 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–see
page 15. These bars are easily changed, Fig. 24. 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 quality precision 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. 25.
* Indicates a caliber specific part. See the caliber conversion
chart on page 16 for the caliber you are loading for.
Fig. 23 - Turning the bolt counter clockwise reduces
your powder charge, clockwise increases the charge.
Fig. 24 - 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.

ones should be used together and the small ones should be
used together.
