The Hornady Powder Measure system is invaluable to the serious reloader. With the case-activated powder drop assembly, it'll fit any press, single or progressive. Pre-set metering inserts deliver precise, repeatable volumes of powder, and are quickly changed, without having to recalibrate for the next caliber. Any type of smokeless powder, from fine ball to large extruded, can be reliably measured. Blackpowder requires the blackpowder version of the powder measure.
