The Lock-N-Load Quick Trickle Powder Measure from Hornady is one of the smoothest operating powder dispensing tools for your reloading bench. This measure is perfect for handloaders who want "hands-on" accurate control of their powder charges. The Quick Trickle provides an excellent way to deliver an initial large volume powder charge, as well as the ability to finish with small precision metering for perfect results. This versatile powder trickler features hand-operated high and low speeds with up to a three-to-one gear ratio. The Quick Trickle Powder Measure is designed with double-sided, sealed ball bearings that prevent stray powder from impeding operation.
