22 Nosler
History of the .22 Nosler Cartridge: Introduced in early 2017
From the Nosler Web-Site : “.22 Nosler is the newest and most diminutive member of
the Nosler cartridge family. While it does not share the same parent cartridge as its
predecessors, it does possess the same spirit in fulfilling an important role.  
The 22 Nosler was born from the idea of creating the most powerful .22 caliber center-fire
cartridge that would reliably function in the AR platform. Compared to the 223 Remington
or 5.56 NATO, the 22 Nosler has 25% more case capacity making it roughly 300 fps faster
at the muzzle for maximized performance.  
How hard is it to retrofit an existing AR-15 chambered in 223 Rem / 5.56 NATO into a
22 Nosler? Switch to a 6.8 Remington SPC magazine along with a simple 22 Nosler barrel
wap and the transformation is complete.
Approaching 22-250 velocities in a significantly smaller package, the 22 Nosler® yields
nearly 25% more capacity than the 223 Rem/ 5.56 NATO making the round capable of
pushing a 55gr. Nosler Ballistic Tip bullet at 3,350 fps out of an AR-15 fitted with an 18”
barrel and a 77gr. Custom Competition® bullet at 2,950 fps
