.22 Nosler

The .22 Nosler is a .22-caliber (.224 in; 5.6 mm), rebated-rim centerfire rifle cartridge designed by Nosler. The .22 Nosler is a SAAMI approved and standardized cartridge. In January 2017 Nosler introduced the .22 Nosler. It is the fifth cartridge designed by Nosler. It is claimed that the .22 Nosler delivers 25% more case capacity and is nearly 90 m/s (300 ft/s) faster than a .223 Remington/ 5.56 NATO. The .22 Nosler is designed to use the existing bolt face of an AR-15, and conversions to this caliber can be accomplished with a simple barrel swap. The shoulder is set back slightly compared to the 5.56 cartridge to prevent accidentally chambering a 5.56 cartridge in a .22 Nosler rifle. The case diameter and taper resemble those of the 6.8mm Remington SPC, so Nosler recommends using a magazine designed for that cartridge. While similar to the 6.8 SPC in some regards, there is no parent case and the .22 Nosler cannot be formed from 6.8 SPC brass. The .224 Valkyrie is a similar cartridge, but the two are not interchangeable.
