Lee Perfect Powder Measure is best for reloading rifle cases, can also be used for pistol cases. Can be used on the included bench mounted stand, or used in conjunction with the Universal Charging Die on the Load Master. Best for reloading rifle cases. Throws charges from 2 to over 100 grains. Eliminates Cut Powder and Jerky Action. A soft elastomer wiper strikes off the metering chamber rather than cut the powder. You'll be surprised at how smoothly the rotor operates. More importantly, you will enjoy the most uniform of charges. Meaningful Calibration 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. So very much better than a meaningless setting as most supply. Versatile 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. The Lee Perfect Powder Measure works fine for charges from two grains to over 100 grains.
