I find this cartridge very interesting.

Well, I liked it when it was called the 219 Donaldson Wasp.

The Donaldson Wasp was used mostly with 1:14 Twist barrels which most likely would never stabilize a 90 grain bullet. The Valkyrie is being tested with a twist rate 1:7 which keeps a 90 grain SMK supersonic past 1000 yards and a BC over 500 at the muzzle.Its very possible that a 22-250 REM cartridge with a 1:7 Twist barrel could equal or outperform the Valkyrie.One of the main attractions of the Valkyrie is it fits an AR 15 Platform and has excellent accuracy in the right hands.

I'm guessing if someone wanted to use the Donaldson Wasp Chamber and cartridge with a
1:7 T/R Barrel might be able to get the similar results as the Valkyrie. Cabelas and Bass Pro already have the Federal Valkyrie Ammo on the store shelves in my area.

From American Rifleman:
"Federal has released some information but is holding some close still, but I can tell you that it's real. I watched Drew and others nail the 1,000-yd. targets time after time, after time. There were also some other very experienced long-range shooters there who dropped the .224 Valkyrie on target so often that it became almost monotonous. And then I stepped back up, focused on the fundamentals and started ringing steel, too."

What about a 22 Nosler?

Nothing wrong with a 22 Nosler especially if someone already owns one. More choices is good.

The problem with high BC bullets in an AR platform is the huge amount of bullet jump from the ogive to the rifling. I have a 6mm Hagar, and to even get the bullets to fit in a cut-out magazine I have to seat them so the ogive is in the case neck.

Of course, you can load them one at a time, but that is worse than a bolt gun in terms of reload time.

Heavy bullets are the way to go, but they don't work too well in AR platform. But maybe in a .22 Nosler or .224 Valkyrie they will work. I suspect the .224 Valkyrie may last as long as the plane with that moniker.

The Weatherby Rifles use lots of FREEBORE where the bullet does not contact the rifling when it is fired and they have a reputation for being great hunting rifles.
The Valkyrie cartridge [6.8 SPC} Federal SMK 90 grain does not have the seating issue you describe with the 6 MM Hagar. The ogive is not buried in the neck of the case.

Don't have any idea how long or popular the 22 VAL or 22N will be around but they have excellent performance right out of the box.

The 6.5 was around for a couple of decades as the 260 REM and a 100 years as the 6.5 x 55. The 260 REM had a very limited following and then came the 6.5 Creedmore. Now almost everyone wants one once Hornady used a different parent cartridge and gave it an unusual name. [Same BASIC performance as a 260 REM] Marketing is everything.

Agree completely

Any idea of the velocities from an 18" barrel?

Looks like a 220 Swift but for heavy bullets.

Here is barrel testing info:

That does look like a nice bullet. I wonder how tough it is. I'd like to try a tight twist 223 WSSM using that bullet. The ballistics are impressive.

AZ, this cartridge won’t have that problem. They pushed the shoulder back until a 90gr SMK fit the neck and the mag.

But I think the sweet spot will be 75s. It’s a 200 FPS jump on 223 at similar pressure and the BC of the 75 ELD-M is .1 better than the 77SMK. All this with 10% more powder so barrel life will be similar.

Just go with the 22 Grendel, 224 LBC, AR, or many other names for the Grendel necked down to .224. Shorter case, same or better velocity, and more room for longer bullets.

Yes do that. Get a wildcat vs a commercial offering that will likely be pretty popular in the AR community and be worth more if you ever sell it.
