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.
