Home Forums Hunting & Shooting AR and Tactical Rifles new Yote rifle

It's a 6.8 necked down to 224 and shortened 1mm(5.56x42). 55gr Noslers are hitting 3500fps out of a 20" barrel. 75gr Amax 3250 at the sweet spot. I've shot the 80 Amax(BC .473) over the chrono at 3050 but haven't shot for groups yet.
If the 80s shoot well at 3050 they will be over 20" flatter at 500yds than the Grendel shooting the 123gr Amax.

Now that sounds interesting.

So I assume you're loading the amaxes at 6.8 mag length?

Yes, 2.295"
Jason Peterson shot a 4.5" group at 1000yds last year using the 80 Amax and N540 powder -3004fps. I think CFE and Lever produce more velocity than the N540 if the accuracy is there at the higher velocities.
I want to see how the 62gr TSX or TTSX does on hogs at 3300fps too.

that sounds very cool.

When can we expect testing to be finalized? This is very intriguing. Could make my 22-250 go bye-bye real quick.

I believe there was a guy on Sniper's Hide that was doing this chambering.

DTech has been chambering the same thing with a 30* shoulder called the 22DTI. Cousin has one and it's running just behind his 223AI's.

The 22 based on a 6.8 case should be much faster than a 223AI, case capacity of an AI isn't even close. 32.5 VS 35.5

There is apx 200fps difference between an AI and the 6.8 based cat.

This version was first chambered in 2007. It's is a simple neck down using 6.8 bushing dies but the case is trimmed 1mm shorter than a 6.8 so the 75 and 80gr Amaxs can be shot from the mag at 2.295.
I've used everything from 10X to RE17 with 75Amaxs and been able to get 1/2" or under groups. I shot 1 group of 5 at 100yds that measured .151", several .2-.3 5 shot groups.

Should get and getting are 2 different things.

Mike sent his load data and cousin was disappointed to say the least. He thought he should've got the 22pdk instead but after talking with a few owners of that one, they didn't get the suggested velocities either.

Mikes max loads were right in line with cousins findings. He did find usefulness in heavier rounds and I'll post some speeds after he gets back with me. But I'm pretty sure he gets 3650 with 50 gr bullets in his 223ai.

He lost a lot of SSA brass at first necking down but finally got it figured out. Just thought it was a lot of work to let a 223ai beat it.

I was wrong he's only getting 3635fps with 50's in his 223ai and he barely reached 3600 fps with the DTI. He could get more but lost cases after 3600.

He's getting 3410fps with 60 gr vmax in the DTI.

Sounds like he doesn't know how to load it if he's getting more velocity from something with less capacity or he's loading the AI a lot hotter than the DTI.
The DTi and PDK are basically the same thing, both have a 30 degree shoulder and add an extra 1/2gr over a 6.8 necked to 22 with the shoulder held to 23 degrees like the 6.8 is.
If you don't have a pressure system to test it's tough to know if you're shooting an AI at 70,000 psi and a DTI at 60,000.
New powders like CFE, 8208 and Lever have come out in the last few years. They are perfect for a case this size. I can shove a lot more CFE ball powder in a case than I can 4895. CFE will show 5000 less psi than 4895 and produce the same velocity.

Dunno, have the 6.8 necked to 6... it never gave the speeds I thought it should either.

BUT even slower, it was accurate and still does everything I would need of it anyway, plus it gets rid of a .277 round which is a great thing... LOL

3,250 with the 75gr A-Max is right there with 22-250 speeds.

Could be uber.

31-31.5gr CFE will get it there out of a 20" barrel.
It has been raining almost every day for 2 weeks here and the range is a mess. When it dries up some I'll get back out there.
I haven't tested much since 08-09 but now with the new powders out the 24x is back on this rifle and I'm ready to reduce the dog population around here. They are eating all the turkey eggs. They are call smart and don't come closer than 3-400.

Really wanted to get a black hole barrel in 22-6.8 to sling gaymaxes.. But now I want to see how the new TMK works at mag length.

The BC of the 77 TMK is .420. Not as high as the 75Amax at .435 or the 80 amax at .473 but it should work. I'l test the SMKs but as long as the Amaxs are grouping under 1/4" I'll stick with them.
I've seen a lot of posts from people saying the BHW barrels don't shoot the solid copper bullets like Barnes and the Hornady GMX very well, have you tried any or have a guess as to why they don't?

I'll not sweat .015 if I can load them at 2.26"

I don't want a weather report.

Get your ass out there.

The new powders may make a difference but here's the load info DTech sent. Cousin was disappointed and thought Mike was too cautious so he worked over only to lose primer pockets. Maybe he has a bad batch of brass, I know his Hornady brass holds up a little better than his SSA but who knows.
