A dual-barrel powder dispenser is provided. The dual-barrel arrangement may offer a highly-accurate, and highly efficient system and method for dispensing a consistent amount of powder. A controller in communication with the interface may determine the speeds at which each barrel rotates in order to dispense a volume and weight of powder from a hopper to a receptacle. A scale may monitor and determine the total weight of powder dispensed into the receptacle resting on the scale. The entire assembly may be self-contained in a single integrated body.
