American Rifleman - July 2017 - 52

Final Thoughts

Nosler achieved its goal with the 22 Nosler. The
cartridge is ballistically superior to the .223 Rem. and
5.56x45 mm NATO in all measures-trajectory, wind deflection and on-target energy. Long-range varminters, as well as
those who use an AR in .223 Rem. for whitetail deer and feral
hog hunting, will benefit greatly. So too will competitive
shooters. I can foresee the 22 Nosler appearing on the firing
lines at National Matches in the not-too-distant future.
From a 24" barrel, the 22 Nosler is capable of .22-250 Rem.like performance-without the headaches associated with the
latter. But, it's not a .22-250 Rem., and it wasn't meant to be.
In addition to efficiency, a consideration for the high-volume
shooter, the 22 Nosler's case design reduces stretching and thus
trimming, keeping you in the field and on the range longer.
The same cannot be said about the .22-250 Rem. With regard to
barrel life, Nosler reports, "One should see approximately 2,000
rounds as used in competition and as many as 4,000 rounds
if used as a plinking rifle." Depending on the source, this is
somewhat better than the .22-250 Rem.
Cost and availability are always considerations.
Currently, only Nosler sells 22 Nosler ammunition and

component brass. Moreover, using
Nosler ammunition for comparison sake, on
nosler.com Trophy Grade Varmint 22 Nosler
ammunition sells for $3.05 more per box
than .22-250 Rem. and $5.55 more per box
than .223 Rem. In the Varmageddon series,
however, 50-count boxes of 62-gr. HPBT
22 Nosler sells for $41.95-a real value.
The primary challenge for the 22 Nosler is
the low cost, diversity and availability of .223 Rem. and
5.56x45 mm NATO ammunition. Hopefully, more manufacturers will step up and bring costs down.
Nosler will be marketing several guns in 22 Nosler,
including: Varmageddon AR (by Noveske), M48 Liberty,
Heritage and Custom. Other rifle makers on board include:
Colt Competition/Bold Ideas, Midway/Bear Creek Arsenal,
AXTS/Radian, War Sport, Barrett, NorthTec Defense,
Noveske, Proof Research and X-Caliber. Now there just
needs to be a value-priced bolt-action.
"If at first the idea is not absurd, then there is no
hope for it." Commonly attributed to Albert Einstein, the
quote is fitting for the 22 Nosler. At first it appears to be
frivolous; however, in time you'll recognize the innovative
nature of its design. I did. That's why there's hope for the
cartridge. It's also further evidence that Nosler is a leader,
not a follower.
22 NOSLER

averaged 3432 f.p.s. for 10 consecutive shots, and the 77-gr.
BTHP CC had a mean of 2928 f.p.s. Standard deviations were
22 and 17, respectively.

The Third Option: Convert Your .223 Rem. AR To 22 Nosler

W

hile it's easy enough to add
a new upper to your existing
AR, or even replace the barrel,
there is a third way to have one chambered for 22 Nosler.
Existing .223 Rem./5.56x45 mm
NATO rifles can be converted to
22 Nosler. It's a gunsmithing project
that requires some time on a lathe, but
it's not horribly complicated and will
probably be less expensive than either
of the other two options.
It's more than just running a reamer
in to make a new chamber, though. The
case lengths of the 22 Nosler and the
.223 Rem. are the same at 1.760", however, the length from the base to the
minimum headspace dimension on the
shoulder is shorter on the 22 Nosler at
1.450", while the .223 Rem. is 1.4636".
The reason is simple, if they were the
same length, or the Nosler cartridge
was longer than the .223 Rem., a
.223 Rem. cartridge would chamber in
a 22 Nosler firearm. This creates a very
dangerous situation if the cartridge
were to fire.
Because of this, the barrel must

52

be set back so the chamber will clean
up at the shoulder with a 22 Nosler
reamer. In this case it must be set back
the depth of one barrel thread so that
the gas port will orient correctly at topdead-center, under the gas block.
The barrel extension must be
removed from the barrel. The barrel is
dialed in and centered in a four-jaw
chuck. The shoulder is cut back the
depth of one thread. The threaded
shank on the barrel must also be shortened by the same amount.
The next step is to cut the 22 Nosler
chamber to the proper headspacing. A
taper is added to the back of the barrel
and the barrel extension is re-installed
and torqued to 150 ft.-lbs. Simple
enough right? In theory anyway.
My reamer is from Dave Manson
Precision Reamers (mansonreamers.com),
and he cautions that this is a tricky bit of
machining because the existing chamber
will keep the reamer from being supported
by the pilot at the start of the cut. With
the unguided reamer, care must be taken
to avoid chatter. Manson said the key to
avoiding chatter is to use an aggressive

feed rate to keep the reamer loaded. I,
of course heeded that advice after first
taking a cautious approach. I experienced
severe chatter in the chamber, but was
able to correct it using the cleaning patch
technique explained on Manson's website.
There is one last thing that needs
attention. With the existing gas port,
the gun will likely be overgassed with
the increased volume of the 22 Nosler.
Mike Lake is the company's senior
manager for engineering, research
and development, and he is the guy
responsible for the 22 Nosler cartridge.
He noted that: "Most standard .223 gas
ports are around 0.090" in diameter.
With the 22 Nosler, we have had good
luck using a 0.078" port and a riflelength gas system."
If you are using an existing barrel with
a larger 0.090" port, the solution is an
adjustable gas block. They are available
from Brownells (brownells.com) in a wide
range of designs and prices. Adjust the gas
volume until the bolt locks back reliably
on an empty magazine and the brass ejection pattern is at about 2 o'clock.
