The American Standard poster contains every Modern Rifle, Shotgun, and Handgun cartridge manufactured in the USA as of 2017. In addition, military surplus and a few bonus cartridges are included. The poster contains 165 unique Rifle Cartridges, 55 Handgun Cartridges, and 9 different Shotgun gauges. This is a living poster. Meaning, once a year it is modified to include new cartridges after they are released to the public. The year located at the bottom of the poster shows the year the poster was updated.
