At SHOT Show 2017, Nosler showcased a new .22-caliber cartridge designed for AR-platform rifles. Called the 22 Nosler, the new cartridge resembles a 6.8 SPC necked down to .22 caliber. Comparing Nosler’s ammo specs with Hodgdon load data, it looks like the 22 Nosler can deliver about 250-300 fps more velocity than the standard .223 Rem cartridge. That’s significant for varminters looking for higher performance from an AR15-type rifle. With a 55-grain bullet, highest possible velocity is 3500+ fps with a max load of Hodgdon CFE 223 powder, based on this Nosler Load Chart:

Nosler will produce 22 Nosler ammunition in various bullet weights, starting with 55 grain and 77 grain. To run the 22 Nosler, an AR owner will need a new upper and 6.8 SPC type magazines. This video explains how to convert your AR-platform rifle to run the 22 Nosler.

“Everything Old Is New Again…”

Examining the 22 Nosler cartridge, our friend Grant Ubl had a case of “deja vu”. He thinks the new 22 Nosler bears a striking resemblance to a wildcat from the 1960s: “The .22 Nosler looks like a throwback to the 1963-vintage .224 Winchester E5 experimental cartridge, right down to the rebated rim.” Here is an old Winchester print:

Another poster said this cartridge resembles the “.220 Thunderbolt” a wildcat devised by John Scandale in 2004. Posting on Facebook, Mr. Scandale said the designs were very similar. According to Keystone Accuracy, the .220 Thunderbolt’s “design origin came from the now largely popular 6mm Hagar in its infancy stage back in 2003.” While it looks very similar to a 6.8 SPC necked to .224, the .220 Thunderbolt is different because the 6mm Hagar brass is 0.100″ longer than 6.8 SPC.

Neck-up the 22 Nosler to .25 Caliber?

Dan Z. has inspected in the 22 Nosler ammunition and he’d like to see a .25 Caliber version. On Facebook, Dan posted: “I got my hands on some of the ammo a couple weeks ago. It does look like a .223 that has its body diameter expanded to that of a 6.8. Consequently, it is longer than the 6.8 overall and in the body. I necked a piece of fired brass to 6.8 and it looked like it would provide some improvement in velocity. A more interesting idea might be to neck it to .25 as a .250 Savage performance clone in an AR-15 platform.”
