The Harrell Premium is the "top of the line" measure; it's large capacity allows it to throw from 6-120 grains. The 16 ounce powder bottle lessens the need to refill as often (also accepts most 1 lb. powder containers like Hodgdon, Accurate, etc). This measure has needle bearings built into each side of the metering insert to give it the smoothest feel of any powder measure we have ever tried. If you want one measure to serve all your reloading needs, the Harrell Premium will give you a lifetime of smooth, accurate powder throwing.
