The ChargeMaster Dispenser has a powder hopper with 1 lb+ capacity, and the powder drain feature conveniently empties the hopper. Its dispenser works with all extruded, ball and flake smokeless powder from 2.0 to 300 grains to +/- 0.1 grain. Dispensing can be done in grains or grams mode. It includes a clear cover for the scale to eliminate fluctuations in weighing caused by air currents without obscuring your view. Power to the Dispenser is provided by the connection to the ChargeMaster 1500 scale. NOTE: The ChargeMaster Dispenser requires the ChargeMaster 1500 Scale (SS# 16540 sold separately) to operate and do not use with black powder.
