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
My favorite firearm has been in my family for four generations. It’s a Winchester Model 60A single-shot, bolt-action, .22-cal. rimfire chambered for the Short, Long and Long Rifle cartridges.
It is not uncommon for useful technical improvements in one arena to be adopted by and integrated into another. Materials and manufacturing processes originally devised for the aerospace industry are now commonly used to manufacture firearms.
