The Hornady Lock-N-Load Powder Measure is an essential piece of reloading equipment for obtaining precise and consistent powder charges to maximize the accuracy potential of your loads. The Lock-N-Load Powder Measure has an extremely wide charge range, capable of measuring from .5 grain to 265 grains. Metering inserts can be changed with the push of a button, enabling reloaders to go from one known charge to another without adjusting powder flow. Tight tolerances between the drum and rotor deliver smooth function with all types of propellant. The Hornady Lock-N-Load Powder Measure can be mounted on a standard mounting bracket and lock ring or, by using Lock-N-Load bushings, on a Fast Load Powder Measure Stand or Lock-N-Load AP with case activated powder drop for automatic powder measuring. Comes with a standard rotor and metering insert, and 2 drop tubes. Manufacturer model #: 50069.
