This instrument provides an extremely fast and accurate method for comparing the shoulder position of fired and/or sized cases and bullet seating depth uniformity. The addition of the “Range Adapter” makes this instrument more versatile and may now be used at the range or in the field without requiring the use of a reloading press.
