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...

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...

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

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...

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....

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...
