Hey Stan, how many feet in front of your barrel was that target? Isn't that gun powder residue I can see? Burt

Default Worth it?

You can bang on me for not helping the economy after reading this, but, eh....what ever.

A 22 Nosler has 34.2gr of H2O at full capacity and 31.2gr H2O with a 55 gr bullet seated. As you can see, there isn't much difference between an Ackley version of the 223 Remington and the 22 Nosler, except thinner chamber walls for 22 Nosler barrels.

At 2.2 to 2.8 more grains for .223 Ackley chamber version a LC Ackley gives 30.6+2.8 = 33.4gr.

So we have this calculation, if you believe Noslers case capacity measurement: 36.9gr/33.4= 1.10479. For a 10.4% gain over a .223 Rem Ackley. Use a shorter barrel on the 22 Nosler and you have lost all the gain in performance that you were looking for. If we use the measured case capacity of someone who actually weighed the case and water capacity, then we get 34.2gr of H2O for the 22 Nosler a net gain of only 0.8grains over LC .223 Ackley brass. The 22 Nosler then has a whopping 2.3% more in case capacity.

That isn't enough gain to sneeze at in my opinion, and it isn't useful unless you have a long barrel. Some bolt gun loads list a .223 Ackley at 2990fps using Varget and 80gr Sierras.

Add an 1.75" to a .223 Rem barrel and that gain is now zero for a 20" 22 Nosler AR upper. What you gain is a lot of BOOM and WOW COOL factor unless you use a long enough barrel to burn the powder.

There is not but a handful of beans difference in actual benefit under 200 yards for a 22 Nosler, so I would instead spend the $ on better optics and bullets.

If your brass is once fired and your chamber is like mine, then your case capacity of neck sized brass using LC brass is nearly 1.0 gr more than unfired brass. Given this, if I just have a 16.25"TC barrel carbine, I am not loosing anything by not having a 22 Nosler except an expensive AR upper, expensive new dies, and a proprietary cartridge that I can't get everywhere, not to mention a shorter barrel life.

If I had a 16.25" 22 Nosler AR upper for some insane reason I would expect 2828fps for a 16.25" 22 Nosler firing 70gr bullets using the best powders on the chart, Varget.

If you really want a longer range cartridge, use the Ackley version of the 22-250 in a proper length barrel.

So, I'll stick with my .223 / 5.56mm case and my little 3.5 pound TC carbine with a barrel I know and trust to put 35 to 70 gr bullets right where I want them, and I'll keep the roughly $3,500 that a 22 Nosler will cost me.

For first time gun buyers a 22 Nosler may make sense in a bolt gun, and the 26 Nosler is a cat with much different spots and it actually does have easily recognized advantages. What are your thoughts or experiences?

Funny you should say that. The 22 Nosler is proportioned nearly identical to the 6.5 Creedmore. Beyond a simple eyeball inspection, if you compare the main case dimensions (less rim diameter) it's essentially a ~9/10 scale Creedmore, with a rebated rim (to get down to the 223 class bolt face). In my opinion this is not by coincidence, Nosler used perhaps the most popular and efficient newer cartridge as their model. And I can't really fault that approach.

I did send a query to Nosler about case capacity. On two different Nosler site pages they state capacity in H2O as 34.2 grs (to overflowing) and 34.7 grains (with a 55-gr bullet seated, on a load data page.) Clearly this is impossible, as the capacity with a bullet seated must be less than the "to overflowing" figure. Unless I'm missing something.

Default Missing anything?

Nope, not missing anything.

If you want to really do something with much better ballistics, then get an AR10 upper for 22 Creedmoor with a 26" barrel.

Over on scout.Com I read the following, but as always, remember to start 10% below and work up in small (half grain or less) increments of powder.

Re: Looking for 22 creedmoor load data

The load I've settled on with my AIAT PVA chambered Muller Works 1-8 twist 26" barrel
80gr Amax
6mm Hornady Creedmoor brass
42gr Hybrid 100V
CCI #200
3530fps
2.081" base to ogive
0.010" jump
I've stretched this out to 1000y with ease and anything closer is a chip shot. I'm very happy with the performance of this cartridge.
semper fi.

What's the fastest 22 caliber that would handle mid weight to heavy VLD bullets well that will reliably feed from a box magazine or ADL 700 without a lot of tweaking? 22-250 AI ?

That would be about the one, 22-250 AI. I see Nosler says their new 22 Nosler is the fastest 22 cal, but they also say in the AR platform, and that is is close to the 22-250's FPS. I for one, will just keep my old 22-250 and if I did anything otherwise, it will be to turn it into a AI version. Bill K

A far more useful case design would have been their variant of the 22 AR (22-6.5mm Grendel). The short squat case and greater capacity would have a much better choice for launching 70+ grain bullets while still maintaining the proper LOA for AR rifles.

I think Nosler chose the 6.8 SPC form factor because SSA was already offering 6.8 SPC brass and ammo.

As far as speed, according the the Accurate Powder manual, if you load the 223 to the 62k PSI NATO spec, it shoots the 55 grain bullets within 100fps of the 22 Nosler. The brass life might not be long at the higher pressures, but then again 223 brass is pretty easy to come by or picked off the ground at the range for free.
