Dillon Precision primer cup spring for RL 550

Dillon Precision primer seating cup spring

The primer cup spring is the spring that supports the primer seating cup in the RL 550 primer slide. It keeps the cup in contact with the primer and allows it to give just enough, providing uniform seating pressure shot after shot.

Dillon lists part number 14033 in the RL 550 primer slide assembly (page 67 of the manual), for both the small and large slides, and in the RL 550B manual parts list as "Primer Seating Cup Spring." The same code also appears in the failsafe rod assembly for the RL 550 (page 65) and XL 650 (page 54) powder measures.

Main features

• Primer seating cup spring
• Original Dillon Precision spare part
• Listed for the RL 550 small and large primer slides

Recommended use

Replacement of the spring when primer seating is irregular or the cup does not return to its rest position on the RL 550. Dillon also lists the same part number in the failsafe rod assembly for the RL 550 and XL 650 powder measures.
