The ChargeMaster Dispenser and Scale work together to achieve an unmatched combination of speed and accuracy. The ChargeMaster Dispenser works with all types of standard smokeless powder and can throw charges from 2 to 300 grains (Not for use with blackpowder). It dispenses 22 grains of powder in 16 seconds and stores up to 30 of your favorite loads for fast and easy recall. Includes a powder drain feature that allows the hopper to be easily emptied. The Scale accurately weighs to +/- 1/10 grain with a 1500 grain capacity and features a large, easy to read display. It can be calibrated with the 2 check weights (included). Both Dispenser and Scale measure in grains or grams and run off the included AC adapters.
