Dillon Precision Primer Slide Stop Nut RL550 and XL650 – 13898

Dillon Precision Primer Slide Stop Nut – 13898

Dillon identifies part number 13898 as the Primer Slide Stop Nut, the stop nut that defines the travel limit of the primer slide. It appears in the RL550 Primer Feed Assembly (page 64 of the manual) and the XL650 Powder Check Assembly (page 56).

The stop nut determines how far the slide advances toward the priming station: its adjustment determines the alignment between the primer and the punch. A loose nut allows the stroke to vary from one cycle to the next and is one of the most common causes of crooked primer seating.
