Redding Reloading Competition Model 10X-Pistol Powder Measure. To achieve the best metering possible at the targeted charge weight of approximately 10 grains the diameter of the metering cavity was reduced and the metering plunger was given the unique hemi-spherical cup shape of our successful Model BR-30. The result is a very specialized small capacity powder measure with a charge weight range of approximately 1 to 25 grains.
