The RCBS® Powder Trickler System speeds up the process of weighing your powder charges. The Powder Trickler system attaches to any Uniflow or standard Quick Change powder measure. Used in conjunction with the Advanced Powder Measure Stand, the Powder Trickler System allows you to dispense and trickle a powder charge directly onto a scale pan without having to remove the scale pan for the initial filling. The unit can be adjusted for right or left handed use and the dispensing chute adjusts to allow you to drop the powder charge directly onto the scale pan. With a few turns of the Trickler handle, your weighed charge is complete. The Powder Trickler System is available as a combo only. Accessory Base Plate not included. Not for use with Quick Change High Capacity, Little Dandy or Black Powder Measure.
