An interesting idea. It definitely surpasses the .223/5.56mm. It makes using heavier/longer .224 match bullets easier in an AR platform too since you can stuff the bullet in deep enough to fit your magazines without sacrificing propellant volume. It gives you considerably more "punch" while still utilizing the lightweight AR15 platform (as opposed to the heavier AR10 .308 platform). I think Nosler is onto something here.

Thank You for posting this.

Oh great, as if I needed to build another upper and stock up yet another caliber.

My retirement dream of two rifle, one pistol, and a shotgun cartridge to keep on hand is getting p!ssed away fast.

Oh yeah, never mind the wife's .380 and my .25 pocket toy.

Meh. Another marketing oriented fix for a non-existent problem that's already been beat to death. But new cartridges and brass for wildcatting is always welcome! I'm sure it'll make a great case for necking up. Plus, if ya hafta run a 24" AR to get the desired velocity, it becomes cumbersome for anything but range work.

I used to run a fast twist (7) 22-250AI set up for the 80-90gr .22's. They're troublesome things and I remember having to walk back loads when the jackets started coming apart right out of the muzzle. Don't remember the velocity. Great for accuracy. Boring for performance. A fast .22 belongs to "exploding varmints". The last varmint I popped with it was a crow at 481 yards with a 90gr JLK javelin, IIRC. It just stopped walking and never moved again. d:^)

One word: Betamax.

A lot of states require a caliber greater than .22 for hunting a game animal of any useful size. As for me and mine, "punch" in a target rifle never made good sense. YMMV.

Always cool to see new developments from manufactures.

Personally though I will continue to stick with my more conventional calibers.
I can make a .223, .243, .308, and .300 Win Mag do anything that I need.

Not discouraging those that work on the wildcat rounds just never has been my interest even though I hand load all my precision ammo.

The biggest difference would be cost and availability of brass. Since I have a kitchen trash can full of range brass for the 5.56, it doesn’t excite me much to pick up 150-200 fps.
