It is currently the fastest production .22 caliber round in the world with muzzle velocities as high as 4,600 feet per second (1,402 meters per second).

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 first AR-15 rifles used a barrel length of 20". In the case of the 223 Remington (M193), ammunition loses or gains about 25.7 ft/sec (7.8 m/s) for each inch of barrel length, while 5.56×45 mm NATO (M855) loses or gains 30.3 ft/sec (9.2 m/s) per inch of barrel length. [18]
The cartridge maximum overall length is nominally given as 2.230-inch (56.6 mm), however, as the cartridge is a wildcat cartridge chamber dimensions may vary from manufacturer to manufacturer. For this reason overall length of the cartridge may vary.
