Nothing yet. My rifle should be in my hands by Sunday. I'll share what I come up with when I get it running.

Curious what you and others think of the cartridge now that the honeymoon phase is over.
These two are almost twins...on the left is a 22 CM 16" #4 Bart, TT 3-15X50 LRH scope.
Got in some really good cold weather testing last week, shooting in temps down to -24F. I learned a lot about small rifle primers in the cold...
Looking for a shortish barrel cartridge for 88s and 90 tips at 2900 or so. More is better but 16-18 is sweet for hunting / field use with the ultra 7.
For y'all who've done it, thoughts on BR (or ackley) vs GT vs CM for a shorty field use 22 cal?
21" with Ultra 7.
90 Atips Virgin brass
40 gr of RL26
Still in early breaking barrel in.
3000 fps with 15 rounds down the barrel.

Out of curiosity, did you ever think about trying a .22BRA?
I would think that a 22" BRA would be able to get some decent velocities, without being as obnoxious of a barrel burner as a .22 CM.
No. Too complicated. It's one thing to change out a bushing in a BR or Creedmoor die you already own but new dies and fireforming? I'm not that dedicated. At that point, why not just go 22-250?
Fair enough.
Fireforming on the BRA's are stupid simple - I wouldn't necessarily call it a con. The first firing is at BR speeds (and BR accuracy), and the subsequent firings get an extra boost in FPS. No need to jam bullets or do anything silly like what you have to do for other cartridges.
I can totally understand not wanting to purchase new dies though, especially for a cartridge you are experimenting with and may not be sold on.
I fireform Dasher. Not scared. But how much performance increase are you really going to get from a BRA over a BR for all that extra?
I would wager around ~80 fps.
Whether that's worth it or not is up to the individual to decide. But an extra 2" in barrel length + FF should put you in the 3,000+ fps range.
I already shoot 6BRA and have BRA brass, so if I was to go with a centerfire .22, a .22BRA would make the most sense to me for my personal situation.
However, I can see why others would be drawn to other centerfire .22 options.
Why go for 3k when you can get 3400?
CREEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEDDDDDDDDDDDDDDDDDDDDD TRAAAAAAAAAAAAAAAAAAAAAAIIIIIIIIIIIINNNNNNNNNNNNNN BBBAAAAAAAABBBBBBBBYYYYYYY
No pressure signs at all with Alpha Virginia brass. Still room for more speed if needed.
Has anyone tried this with 85.5 Bergers and what kind of velocities are you getting with Varget/H4350, ect.
Still waiting on my barrel, but whidden 6gt bushing FL sizer and "The Seating Die" from SAC.
You should be able to up that speed i would think. My 22br ran up to 3150 with the 88's and 31.5 grains n550. I backed it down to 3020 and 30.3 grains where i found a good load. My barrel is 23".
22Gt and 22-250 should be exceeding the BR quite easily
What is the oal of the 22gt? Could a person run one in an ar15?
Wanting to build a couple better .22 cal rifles, same caliber for in a bolt and ar15. Been looking into a 22br, 22 grendel and a 22gt. What are the case lengths and oal case lengths for all 3? I think the gt would be sweet but not sure if it’s an ar15 capable cartridge.

I think so. Its still early on this barrel and I switch to N555 powder due to availability. Problem with N555 is the charge approaches being compressed around 38.0 grains. I was using H4350 early on but powder was very low. Also, ran non-magnum primers. Still working on it, but its good enought to shoot coyotes for now.
OAL on the 22 GT would be too long and there's a bolt face problem. Feeding in AR mags would probably suck too. 22 Grendel is your best bet. I have one. OAL with 88's pretty much runs right up to AR mag length.
thread drift but who makes 22 grendel barrels nowadays?
I’m getting ready to ask a place on Facebook. Baldwin gun works do the grendel and I seen a post about them doing a 6gt in a ar15. That’s way I asked the question here about a 22gt in a ar15…..figured someone surely would know more here.
Isnt this what 224 valk and 22 nosler were competing over when they came out? Could try lookin in one of those threads too
Hate the 22 nosler brass trasher and I have a Valkyrie but it’s so damn finicky to the point it’s not that fun to reload for. I pissed away a lot of time, resources and components just in my bolt gun to find what works so so and I’ve seen what experienced ppl gone through to try and get an ar15 in that chambering to shoot…….I will never have an AR Valkyrie. I’m looking for something faster with better brass even though I have probably 300-400 once fired starline brass. If I could seek out of the Valkyrie I probably would. I have a love/hate relationship with the Valkyrie.
Someone in the gt fb group has posted about a gt on the ar15 platform that they put together.
Anyone using varget?
