This Gauge Will Measure:
— Maximum Cartridge Length (COL)
— Minimum and Maximum Case Length
— Maximum Case Diameter
— Minimum and Maximum Headspace
Easy as 1, 2, 3!
1) Place a clean cartridge into the gauge and make sure that it completely seats by itself with no assistance. If the cartridge does not easily drop into the gauge without assistance, there is most likely something wrong with the dimensions of the cartridge.
2) The head of the brass should sit flush within the lower or upper step of the gauge. If the cartridge sits higher than the upper step, your brass is too long and may not chamber.
3) Also check to make sure the tip of the bullet is not protruding beyond the face of the gauge. If the bullet tip protrudes from the end of the gauge it is longer than the maximum allowed cartridge length.
