Have you seen the DTI line of 6mm's? They are based off the 6.8SPC instead of the Grendel. Basically ballistic twins depending of whether you prefer using Grendel or SPC brass.
The 6mmDT is just a neck down, but the DTI is blown out increasing capacity like the Turbo. Since making the DTI he doesn't make the DT any more.

BTW if you don't know who Dtech is... Mike Milli of Bemidji Minnisota. One of the fathers of off caliber AR's. His rifles and barrels are world famous and sought after in the hunting AR community.
If his guns don't shoot under MOA he wants them back to find out why! Most are well under 1/2 MOA.

HUGE +1 For Mike's stuff. I have a 25 DTI with an 18" barrel which is a 6.8 SPC necked down to .257 with a blown out shoulder. Single pass in the die, load and virgin brass is still shooting well within sub-MOA. With once fired brass 1/2 MOA is cake. It'll put out 90 grainers at 3k+ so it's a performer too. I've got him building me a full tilt varmint 223 upper as well right now since his price for the quality is cheaper than I can do myself mainly because of his deal with Shilen for the barrels. Great dude to deal with but if you want to talk you have to call right away Monday or Thursday Mornings as he doesn't answer the phone outside of those times otherwise he'd never get anything built.

His prices are great for what you're getting, but I will say the wait time is long. My 25 I ordered back in March of last year and got it in Feburary. And when he called to let me know it's done, I ordered the 223 and he said about 13 months. But IMO the wait is WELL worth it for his custom stuff.

Here's his website if you want more info.
