Redding Reloading Equipment recently introduced the Competition PR-50 powder measure ($210, MidwayUSA.com), which is geared for precision rifle shooters and the specific cartridges they favor. This is Redding's fourth model in their series of weight range specific powder measures. The company began building specialized measures for various shooting disciplines and cartridge types over 10 years ago; beginning with the BR-30, Competition 10x and most recently the LR-1000.
Redding knows that any volumetric measuring device carries a sweet spot that is relative to the dimensions of its metering chamber. The greatest precision and repeatability is found within this sweet spot, with an increasing level of consistency degradation happening as charge weights move farther out of its range. Broad range measures are good throughout their range and great at points. In that tradition, the Competition PR-50 was engineered with a sweet spot from approximately 35 to 75 grains of most powders. This new measure completes the group, with a total of four distinct powder measures, each optimized for incredible precision within a given range of charge weights.
The company says that consistent charges are assured by a precision ground drum, a honed metering chamber and a unique hemispherical micrometer adjustable plunger, which eliminates powder voids caused when using long grain powders. Additionally, the micrometer is designed to reduce backlash in its travel, allowing for easily repeatable charge weights.
