Speculate and discuss.......

extra long rimfire!

Overbore.......

22 Dasher clone

Something in the 22/243 or 22 Creedmor range .

I'm sure someone has already necked one of the Creed cases down to .224......

22-250ai - ish...... Twisted right it could definitely be da bomb 🚀

Heard a rumor that its for ar-15 receiver rifles. 77's at 3300 fps.

Since we're speculating and discussing, might as well add 24, and 25 Nosler to the conversation.

The 22 is real....the others not so much......

True. But given Nosler's propensity for bringing us new chamberings, it only stands to reason the the 24 and 25 Nosler are waiting in the wings.

.22-204

Yawn, as with most of their stuff given my needs.

6.8spc necked down is my guess.

22-204 would be a good a guess as any.

Makes me think about Steve timm saying a 223 AI clone was almost released some years ago, with a major bullet manufacturer doing the load work up and pressure testing, but the rifle manufacturer got cold feet.

Hope SSA/Nosler improves the quality of the 6.8 brass if so. There are various .22 and 6mm wildcats on the 6.8 case and they are good cartridges, but my experience (and others) with their brass has been sub-optimal from a QC and durability standpoint.

This ^
my fave walk-around round ( plus the 6-204 for legal deer )

Needs to fit within the magazine constraints of their chosen platform though. Gets 223 AI velocity w/o the excessive pressure.

Given Noslers LR focus with the 26,28,30, & 33; I would think that a .22 Creed or .22-243 might have the velocity to drive 75 grain + at reasonable pressures.

Carry On

If they legitimized the .22-204 they'd score points with me, but I'm guessing it'll look something like a .22-243, with a 30 degree shoulder.

Where is this latest Speculation Arising From ? Hints from Nosler ?

.22-243 30, .22-Creed, .22-250 Improved are all very similar in capacity and capability.

It's more about OAL, Twist, and throating in a 2.8" magazine, than exact details of the chambering. I like a longer neck for target shooting volumes.

For my purposes, the .22-204, or even the .20 practical is more suitable than the larger cases.

It won't be able to hang with the .22 Eargesplitten Loudenboomer . . .

.22-17 WSM ?

Thought that was called a 222 Remington Mag?

About the same difference as a 7mm JRS compared to 280 Improved

It is.......if you consider a case body with less taper, a sharper shoulder, and said shoulder blown forward .075" the same......

Picture on brass box, looks like a 22x57 - 6mm Rem, Creedmoor 30 Improved

Drawing on AS looks like .22-6.8SPC

Speculation is rife !

Too big.....57mm = 2.244"

I'm guessing a 6 Hagar necked down.

Claim is 70's at 3300.

Should of standardized the 22creedmore

You mean do the .22-250 Improved all over again?

Believe it's to be geared towards the AR-15 platform.....

The Creedmoor is even more Improved with a .462" shoulder diameter vice .454" for the AI. Angle is 30 degrees vice 40.

So it is the .22-250 Creedmoor Improved 30


Should add that this isn't that

Is the diameter of the Hagar between a .223 and a 22-250?

Seems like it uses a non-standard parent case.

338Rules,

I didn't say .22-250 Ackley Improved, I said .22-250 Improved. The Creedmoor case is so close to the old .22-250 RCBS Improved (which had a 28-degree shoulder) that a .22 Creedmoor just might fit in the chamber, with all the attendant problems of varying chamber and, especially, throat dimensions.

Sometimes that causes factories to back off from standardizing certain wildcats, and sometimes it doesn't.

As usual you are spot on, John.

The RCBS Improved 28 degree shoulder is awfully close to the current 30 degrees that is in vogue. My main point was the extra shoulder diameter of .462" in the Creedmoor shoulder geometry, which in turn contributes to the case volume.

Happy New Year !

I'm guessing that it is a necked down Hagar.

"The 6mm HAGAR was derived from the 30 Remington and it has the same case head diameter as the 6.8 SPC, also a 30 Remington derivative."

Thus, a necked down 6.8SPC by most accounts, though the Hagar case is a decent bit longer than the SPC.

Zzzzzzzz......

Interesting.




Travis

Supposedly uses a #10 shell holder, meaning a rebated rim.....

Yes it sure does...I wonder if it will do what a .223AI will do?

Sounds like the 220 Thunderbolt or 240 Tomahawk as developed by Keystone Accuracy off the SPC or Hagar case. A rebated rim makes no sense for an AR based cartridge because of the availability of SPC bolts, but I guess it might for a bolt action to utilize the standard .373 bolt face of the .223 Rem.

Hard to beat the standard 22-250 with fast twist barrel like a 1&8 with Hornady 75 gr A-Max bullets

If Nosler would have built it for the 75 Amax to run in AR mags, it would have a chance. Pretty stupid.

Maybe so, but with no fireforming...

Here are a couple of cartridges made on the the 30 Remington case.

223 for comparison.

6MM Rimless Wasp at a case length of 1.765
22X30 Remington improved case length of 2.040

I'm guessing they are trying to max out the 22 caliber in the AR magazine constraints. A simple neck-down of the 6.8SPC would be a pretty good number.

If that is the goal, sign me up.

Beats the hell out of all this 6.8 and Grendel schit.




Dave

dogzapper just posted over in the gunwriters forum. Apparently it's the 223 Weatherby...

The case drawing is not a 223 Weatherby, unfortunately.

It appears to have the case head/web dimensions of the SPC/Hagar which are built off the old 30 Remington.

30/06 accelerator?
