The Redding Competition Model 10x Pistol and Small Rifle Powder Measure has been specially designed to provide the highest level of metering possible at a targeted 10-grain charge weight. This measure has an accurate range of between 1 and 25 grains, which makes it perfectly suited for both small rifle calibers and nearly all pistol calibers. Not only is the Redding Competition Model 10x Pistol and Small Rifle Powder Measure highly versatile, but it features a test tube-like bottom that ensures consistently accurate metering. You can also change the drum assembly from left-hand to right-hand operation if needed.
