Powder pours uniformly from measuring cylinder into case, thereby eliminating the hazards of "overloads" caused by clogging when charges are "dumped". Changes easily from charge to charge without emptying powder hopper. Numbered measuring screw is used for reference to find a given charge at a later date. The measuring cylinder has precision ground surfaces and slides into the honed main casting for a precision fit. Standard 7/8"- 14 thread. Includes stand plate, drilled for easy mounting on a bench or under a reloading die lock ring. Two drop tubes for .22 caliber and up are supplied. The Uniflow Powder Measure is fully capable of accurately measuring all three major powder types - ball, cylindrical, and flake. NOTE: The Uniflow Powder Measure should be used in conjunction with an accurate powder scale for setting the original charge and for checking charges occasionally during the run.Not for use with black powder.
