||The Competition Model BR-30 Powder Measure is truly a competition model with some very special features. One of these features (the new drum and micrometer) limits the overall charging range from a low of 10 grains (dependent upon powder density) to a maximum of approximately 50 grains.
As a result we do not expect this model to be the proper choice for everyone. If, however, you are a serious competitive shooter and all of your loading requirements are between 10 and 50 grains, this is certainly the measure to choose.
We have used all of the competition proven features of the Match-Grade Model 3BR and designed an entirely new competition micrometer and drum. To achieve the most uniform powder metering possible for Benchrest Competition at a targeted charge weight of approximately 30 grains (hence the name BR-30) an entirely new drum and metering unit was needed. The diameter of the metering cavity was reduced and the metering plunger was given a unique hemispherical or cup shape.
This shape creates a powder cavity that resembles the bottom of a test tube to alleviate irregular powder settling and to enhance charge to charge uniformity.
A special operating handle was also created for this model. It's a rotating handle, slightly heavier to help you maintain a more uniform stroke.
