RCBS® Competition Powder Measures accurately meter, by volume, all types of smokeless powder—ball, flake or cylindrical (stick). The pistol/small rifle model measures .5 to 40 grains, the rifle model meters 10 to 110 grains, and the combo unit handles both ranges. The units combine the proven Uniflow™ Powder Measure, which features a precision-ground metering drum and honed main casting, with a powder baffle and Micrometer Adjustment Screw. The Powder Baffle controls the powder flow and the pressure of the powder column on the metering unit. The Micrometer Adjustment Screw allows precise adjustments to the metered charge and lets reloaders record the number for future reference. The handle can be positioned on the right or left side. Note: The Competition 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. Do NOT use with black powder.
