Home Forums Hunting & Shooting Ask The Gunwriters 22 Nosler...?

No idea, but I'd guess 1:12 or 1:14.

I pulled one of the Oehler test sheets from my file. The barrel is 26-inch Wiseman, but the twist-rate is not identified.

The particular load on the sheet is 31.0 grains of H-335 behind the 40-grain Ballistic Tip. Muzzle velocity averaged 4,111 fps; ES is 38 fps and the SD is 14.

The five-shot group measured .39-inches.

Interestingly, they identify the brass as Federal; why not Nosler????

Below is the data sheet from Nosler. This might piss off some industry folks, but I'm not a part of the firearms industry any more ... as if I ever was.

They would be missing the boat if they twisted that at 12-14"


But boats have been missed before....

For no practical reason, I would prefer to see it be a .220 Swift AI without the semi-rim. Seems it would make more sense and be more in keeping with the apparent philosophy behind their other proprietary rounds (bigger, faster, badder, long-rangers.) It could make a sizzler of a varmint round and they might even develop a bullet in the 70 - 75 grain range specifically for pronghorn, deer, whatever...

I don't see where much of anything else mentioned as possibilities doesn't do much that's not already being done.

Glad to see ya come clean.....I've know about that for quite a while, and a pity they didn't follow through.

However, I don't believe the case print of the new round is close to the 223 Weatherby.

Steve,

Thank you. Always wondered about that.

very near 6mm Hagar case dims

Steve,
Do you have the case dimensions for the abandoned 223 Weatherby?

Thanks!

The 223 Weatherby would be a fun round, for sure. Why would they wait on that one?

The ammo , 77 grain.

Good to see this..if they are loading 77 grainers, they are twisting it fast....

My thoughts exactly. From Nosler's own webpage, here is a 77gr .22 bullet. Note the twist requirements.

This could be good......hope somebody besides Nosler chambers a proper rifle for it...

Just saw this, some pictures of the 22 Nosler and the cartridge dimensions.

Interesting.

Steve,

The .223 Weatherby (like the .223 AI) did NOT get those velocities at those pressures, which is why Weatherby abandoned it.

The original pressure-testing was done with strain-gauge equipment, which can result in unreliable pressure readings, due to several factors, often lower than actual pressures. Strain-gauges can work fine, but since there wasn't any "reference" ammo there was no way to check the original load work-up. More work in other labs indicated pressures were much higher.

This happens occasionally. Chub told me years ago that the Nosler lab's results with the .257 Roberts Ackley Improved showed higher velocities with less pressure than the .25-06, which has at least 10% more powder room than the .257 AI. But neither of the two major piezo pressure labs I'm acquainted with have ever been able to find any magic velocities due to case shape. Instead they report that the only way to get more velocity at the same pressure is to use a larger-capacity cartridge.

The reason many wildcats SEEM to produce the same velocity as larger cartridges is traditional "pressure signs" normally don't appear until pressures are in the 70,000 PSI range, and often even higher. This is exactly why 7mm STW velocities reported by various shooters (including Layne Simpson) dropped around 200 fps when Remington introduced the STW commercially. Widely-used handloads developed far more pressure than SAAMI considers acceptable for ammunition to be fired in a wide variety of rifles in a wide variety of conditions.

Looks like they designed it for AR rifles which I have no interest in since they are restricted here but I would have interest in a bolt action or single shot rechambered to the 22 Nosler.

I have a Interarms Mini-Mauser that could be re-barreled to .22 Nosler.

Should be a fun little cartridge to use on coyotes.

Looking at the cartridge dimensions of the 223 the 22 Nosler is a bit shorter so a 223 would have to be set back first and then rechambered. Case length and OAL are the same.

I think it'd be a waste of time in a bolt gun.

That may be but I'll still think about it..........
