Thanks for the feedback everyone. Very helpful! Key takeaways are that going with a short action Tikka caliber does not offer much weight savings. Secondly, choosing a "Light" Tikka barreled action versus the Superlight might offer benefits in accuracy and cost without much of a weight penalty.
I also agree with Lefty on the scope comment. Below is a picture of my stock Tikka T1 Superlight in 30-06 with a reasonably light scope - 7 lbs, 8 ounces! I could cut another 5-6 ounces by going with a Swarovski Z3. There are also some stocks now being made for Tikka's that are even lighter, enabling another 4+ oz reduction. I think its very possible to get a Tikka barreled action below 7 lbs - amazing. Right next to it is the picture of my best group with my Superlight 30-06 with handloads - .06". Looks like one hole. Everyone I know with a Tikka has a better than .75" MOA gun.
I also really like to use Arca Swiss with tripods when hunting out west. The final picture is my Tikka with a Grayboe Phoenix. Really changed the feel of the rifle for the better, and it is fantastic on the mountain. Tikka's are an incredible value for their weight and accuracy if they make the caliber you want - how about a 7 PRC soon Tikka?
