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 )see Figure
21). These adjustments are accomplished with a case in the shellplate and alternately
raising and lowering the operating handle, while adjusting the powder die (see Figure 19). When properly adjusted, the powder bar will be moved to
its full rearward position by the case (see Figure 21).

The powder die can be easily adjusted by turning the die beneath the toolhead while
holding the powder measure securely from above. |

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 (#13960) to the bellcrank (#20339) by releasing the throttle clip (#13929). See
the RL 550B Parts List and the RL 550B Schematic. Place the clip on the
bellcrank (#20339) align the holes, reinsert the powder measure rod (#13960) through the
holes and clip in place. Lower the operating handle (#20636). Insert the powder measure
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 Fail Safe is to return the
powder bar to its closed position should the springs fail to return it. |
