I went with the 22-250ai. Thanks everyone.

That's a good choice. Given the plethora of factory ammo brass is everywhere. Did you decide on what twist and length?

8", 26"

Just did some case capacity measurements. I didn't have 6.8 case on hand, but Nosler says the 22Nosler capacity is "about" 25% greater than a 223. LC 5.56 cases hold about 27gr of RL-17 to the base of the neck. Multiply by 1.25 and you get "about" 34gr. For comparison, my Lapua 22BR cases hold "about" 35gr.
So it does appear that the 22Nosler has the potential to give very impressive performance in the AR platform for which it was designed, given that 22AR ballistics are well known and the capacity of that case should be very close to the 22BR.

THEY GOTTEN THERE WORK CUT OUT IF THEY THINK THAT 22 NOSLER WILL SURPASS THE 22BR ITS BEEN AROUND ALONG TIME FOR SOME NEW CAT TO TAKE OVER

22-250 or 250AI, 22x47L or 22 creedmoor with 8 twist tubes for the 80/80.5's. I run a 22" 8tw in 22 creedmoor and it's a sweet shooting round. Plenty flat and just wrecks hog and coyotes. I run the 80.5's at around 3450-ish. Still working out the load, but based on drops, I am in the neighborhood.

If you had a 223 action, I would say 7twist 223ai and run the 77 TMK or 80.5 berger.
