Nosler Custom decided to go down in size, but not performance, with the new 22 Nosler cartridge. It sends a .22-cal., 55-gr. bullet 3350 f.p.s. from the muzzle of an AR-15 platform, duplicating .22-250 Rem. performance. Nosler claims its new cartridge can get 300 f.p.s. and 25 percent more energy out of the AR-15 platform. Also in 22 Nosler is a 77-gr. Custom Competition bullet at 2950 f.p.s. The genius of the 22 Nosler is you can use your own AR lower receiver, but you need a magazine that can accommodate a slightly longer cartridge overall length—like the one provided by the 6.8 mm SPC, which just so happens to fit in a standard AR magazine well. If you can drop a magazine and fieldstrip an AR, you can turn your existing .223 Rem. AR into a 22 Nosler. nosler.com
