Is There a .22AR Cartridge?

[Bully]

I believe I read or saw somewhere something about a .22AR cartridge. My designation may be incorrect and if so, please correct me.

It's a 6.5Grendel case necked down to accept .224 bullets.

If anyone has any info or can tell me where to find info, I'd appreciate it.

Thanks a ton.

Yup.....224 AR


Me thinks that I will have to explore this one further with the 69 TMK or 75 Amax for calling.......

 

[Bully]

Thank you.

I love the concept of this cartridge however since I'm not a gunsmith I don't know if it's a financially viable option.

Robert has a smith, with the reamer, and some videos of the brass making process.

He also sells the brass and dies, with bushings, required for forming the brass.

Check out his site and decide if it`s worth it to you...

There is a 22x6.8 spc as well, just like the Grendel the 6.8 is necked down to 22 cal, only thing is lapua don't make 6.8 brass but does the 6.5 Grendel if that even matters. Runs with the 22-250 speed wise.

I don't know if it's a financially viable option.

Since WHEN does that come into play?? You've got the bug, you're hooked, and you're only going around one time (unless you're Shirley MacLane) so enjoy the hell out of it. And nothing anybody else says about the subject makes any difference till you've done it and found out for yourself.
Kinda like movie critics. They think the movie was crap but YOU liked it so THAT'S all that counts.
If you build one, PLEASE report on your findings.

 

[Bully]

It's not. I went with a 6.5G for the moment.

In a few years, if I still have the itch, I'll neck the brass down and grab a barrel.

Nosler is coming out with 22 nosler. It has a 223 bolt but it will need a 6.8 case

Take a look at ARP Barrels, they offer a AR-15 barrel called .224 Predator for $200

www.ar15performance.com/grendel___misc_barrels

I copied this from their website:
Part of our Predator line of barrels, this cartridge is based on the PPC or Grendel brass. There are several names for all of these cartridges such as " 224AR", 224LBC, 223 Grendel. All 3 of those belong to certain companies and all 3 are the same cartridge. Whatever it is called it is capable of pushing 80gr bullets with a BC of .445 to 3100fps out of a 20" barrel making it one of if not the flattest shooting long range cartridges to fit in an AR15. 55gr varmint bullets will hit 3500fps and 40gr bullets 3700+. The 224 Predator will do everything a 20cal. will and more

DAMN YOU!!! (I am 1000% kidding)

I just found out about a group buy on a Grendel barrel but this is just such a cool cartridge. I may have to call them and see what they have to say about it. Thanks a bunch for the info.

I'm wondering necking down involves as they only offer a 2 die set. I have just acquired 50 pieces of 6.5G brass from Hornady and can anneal it if necessary to facilitate the process. GAHHHHH!!! Too many choices!

 

[JORTZ]

Im in the same dilemma right now. I was going to build a 6mm ar then i saw the 224 ar so im doing the logical thing and build both lol

One might be able ro go straight from 6.5 to .224 but I find that using a 6mm PPC full length die as an intermediate forming step makes it a lot easier.

For me, getting to .224 is the second srep on going to .204 for my 20 Grendel.

BTW, I set the die to to size only about 2/3 of the neck length. The tiny shoulder is enough to help get the metal to flow more smoothly into the smaller diameter.

So, just so my lightly addled brain is clear: You bushing/neck size, then full length size in a 6PPC die, then bushing/neck size to final diameter?

Starting with unfired brass, I then use the 6PPC Full Length die, followed by the 22 PPC Full Length die, then the 20 Grendel Full Length die.

Subsequent firings use the bushing die.

I'm pretty sure Hornady would build you an intermediate forming die and life would suddenly be much simpler.

Yes, Fred at SABRECO in Skippack, PA.

I USED to own a Grendel. It had two problems.
First, the bolt had to be thin to accommodate the larger case head. This necessitated an extra strong (expensive) bolt and also limited chamber pressure in the AR platform.
Second, the brass was thin at the web to accommodate more powder. After four firings using AA's load data, my expensive Lapua brass was toast. For comparison, my Lapua 6BR brass has lasted more than 100 firing with hot loads (105gr at 2950fps)
Some say, well what about in a bolt gun? WHY? The whole idea of the Grendel is a COMPROMISE to get max performance is a mag length AR. There is no reason to consider the Grendel platform in a bolt gun when you have the excellent and proven BR platform available.
The BR/AR fixes the brass problem but makes the bolt problem even worse.

The 22Nosler is a game changer that fixes the bolt issue with a rebated rim.
Only time will tell about the brass. I feel confident that this cartridge will be very popular and I'm going to wait until Lapua makes brass ("when", not "if") because I have not had good experience with Nosler brass toughness (read Norma).

The only drawback to the 22Nosler that I see is the case is too long to accommodate 90SMK's at mag length. This is important because there is a such a huge disparity between the BC of the 90gr (.563) and the 77/80gr (.42). My plan is to build a 22DTI (available now, I just talked with DTI yesterday) and use 22Nosler brass F/L resized in the DTI die with a .223 bolt head. This solves two problems simultaneously. First, it allows 90grSMK (ogive .638) bullets at ASC mag length (2.315) and DTI "trim to" length (1.676). And second, it negates the need for fire-forming. The difference in capacity between the two cases is negligible.

The 22PDK is very similar, and was available at one time from WOA, but the DTI may have made the PDK obsolete. Not sure because I haven't talked with WOA.

I have already brought this case length issue to Nosler's attention, but their "ship has already set sail". It still should be a great cartridge for hunting or single load AR use.

Coincidentally, announcement of the 22Nosler came at SHOT 2017 only 11 days after you posed your question.
