There are three small arms items that do not use any color code. These are standard ball, national-match grade,
and high-pressure-test rounds. The standard ball cartridge has no special markings. The national-match-grade
round always has the letters "NM" stamped on the cartridge head. The high-pressure-test cartridge has the
letters "HPT" stamped on the cartridge case head.
