MVA MICROMETER ADJUST SCALE

This scale is adjustable in .001″ increments by loosing the knurled lock screw on the side, rotating the adjusting ring to the desire setting, and then tightening the lock screw. This scale measures .500″ outside diameter with a 7/16″ inside diameter. It is adjustable from 9 grains to approximately 125 grains of FFg powder. Some volume variation may occur when using different granulations and brands of powder. Additional scales can be purchased for $50.

    I bought this scale for use in my vintage Belding & Mull powder measure for charging larger capacity smokeless powder cases. The scale is well made and nicely marked on the slide and the micrometer adjust knob and easy to read. I like the markings much better than what are on my original B&M micrometer drop tube. I will likely use the MVA scale exclusively for all my powder measuring since it is better marked and easier to read than my original B&M drop tube.

    Since the O.D. of the MVA scale measures exactly 0.500″, to use it in my vintage B&M measure I had to machine down the outside diameter of the tube a few thousandths of an inch for it to readily fit in the bore of the B&M measure which also exactly measured 0.500″. This was an easy process with a metal lathe, but might be harder to do if one does not have access to a lathe.
