By pure volume of sales, 22LR Ammo is by far the most popular bullet in the world today. This ammo originated right here in the United States in 1884 by the Union Metallic Cartridge Company. The 22LR round is extremely versatile, as it can be loaded in pistols (even Glock), rifles, revolvers, and shotguns! Even Heckler & Koch brought one of their keystone firearms to market that is chambered in 22LR, the MP5 22LR !
