A soft elastomer wiper strikes off the metering chamber rather than cut the powder. A nylon cone shaped drum adjusted to zero clearance. The nylon is self lubricating so it will never bind or wear out. A micrometer adjuster that reads directly in cubic centimeters. Just multiply the charge in grains by the cc for one grain and you have the setting. "O" ring positively locks the adjustment and removes all end play. The metering chamber is the proper size for large rifle charges and the strike off opening small enough to work well with pistol size charges. Works fine for charges from two grains to over 100 grains. Rotate the hopper 1/4 turn to shut off the powder flow and the hopper can be lifted off. You can empty the hopper from either end. The valve is also a powder baffle which contributes to the unusual accuracy of this measure.Tapered drop tube quickly passes the powder without bridging. Optional Universal Charging Die makes the case operate the measure. Includes adapters to fit almost all cartridges.
