Also referred to as “The Case Gauge,” this item is designed to measure:

1) The curved “banana” shape of the cartridge case;

2) The relative wall thickness variation of a cartridge case;

3) The cartridge case head out-of-squareness;

4) Individual Bullets – out-of-round “egg shape” and/or

curved “banana” shape (excepting very small bullets);

5) The seated bullet and cartridge runout of loaded rounds. The accuracy of any firearm is determined — and limited — by the quality of the ammunition shot in it. The effect of imperfections in ammunition is cumulative;
