Dillon Precision blue failsafe return rod for RL 550 and XL 650 powder measure

Dillon Precision Blue Failsafe Strip Nut

The blue failsafe nut is the adjuster that regulates spring tension on the Dillon powder measure failsafe rod. Adjusting this nut sets the return travel of the powder bar, which is the movement that returns the powder bar to the charging position after each stroke of the lever.

In Dillon manuals, the correct adjustment is achieved by leaving approximately 0.030" of clearance between the coils when the spring is fully compressed, a value that may require fine-tuning after setting the case mouth flare. The part appears as part number 13799 in the powder measure assembly of the RL 550 (page 65 of the manual) and the XL 650 (page 54), along with the Tinnerman insert 13801 and washer 18086 of the same failsafe rod assembly.
