OP:
I love both, but I decidedly voted for the Tikka.
I built a lightweight AR-10 (actually DPMS LR-308-pattern) in 6.5 Creedmoor. I love it. It was ringing steel at 871 yds with aplomb, and is making my Snipers jealous a little. It was so accurate it was boring. It's light enough that the heavy Sig Tango6 is noticeable up there.
It's a:
Gibbz side-charging upper, Proof CAMGAS 20" carbon fiber 1:8 tw 6.5cm barrel, JP HP BCG, Midwest Industries low-height rail.
TN Arms polymer lower, Trigger Tech trigger, Magpul MOA K2+ grip and ACS-L stock, JP SCS buffer.
For an AR-pattern rifle, it's very light. But I'd not confuse it with being actually light, nor something I'd want to carry in the mountains. Just because I did carry an AR in 7.62x51 in the mountains once upon a time, doesn't mean that I want to volitionally.
For a rapid-second-shot tool, like a prairie-dog rifle, it'd be great. For a big-game hunting rifle, it's not my first choice. But it was REALLY fun to build, and so satisfying to shoot.
That being said, I'd echo the previous suggestion and perhaps purchase a Tikka CTR for your hunting rifle, plus consider building yourself a 6.5 Grendel for the AR. The AR-15 size has far more standardized components, making plug-and-play easier. The Grendel is plenty for deer or coyotes or prairie dogs, is FAR lighter, and more enjoyable to carry. And for targets/steel it's still plenty to get to 1000.
I love my AR 6.5cm; I LOVE my AR 6.5G.
