The Redding Competition PR-50 powder measure is the fourth in a series of "weight range specific" powder measures Redding has produced. The Competition PR-50 is for the precision rifle market and the specific cartridges associated with it. It was engineered with approximately 30 to 80 grains of most powders and its charges are assured by a precision ground drum, a honed metering chamber and a unique hemispherical micrometer adjustable plunger which virtually eliminates powder voids caused when using long greain powders. The micrometer is designed to reduce backlash in its travel making for easily repeatable charge weights as well. Mfg: Redding
