Good luck with your new toy.... when you want to upgrade your Tikka barrel, pm or email. Anything is possible.
I suspect that once you get into the sport, you will move away from the 308Win as there are so many other options with less cost, recoil. But if you do decide the 308Win has your heart, there are precious few bullets you will want to use that need anything faster then a 10 twist.
FYI, been competing in FTR with the 308win for a long time... at long range. Built the rifles, shot the bullets.. plenty of real world data.

This will actually be my first bolt action! Ive shot quite a few different ones but settled on the .308 as I wanted a bit of punch, and have a local range with 900m I can use (When I acquire the skill of course), but can work my way up to it and wanted a capable cartridge.
My other choice was a 6.5cm but wanted to keep ammo cost a tad bit lower as I go to the range once a week and plan to shoot around 75+ rounds through this thing. I do however have a feeling that ill enjoy this for a while, then as you mentioned, move up to something else, likely something custom, but in the mean time, I figured this would be a fun caliber to learn on!
I am very enthused about this rifle, I am picking it up friday, and already have plans to go to the range (shooting edge YYC) on the weekend (which is why i was making the trip to YYC), so ill bring it out of the box and just shoot it without a scope.
In the meantime, I was recommended 34mm vortex rings as I am planning on getting a Bushnell Match Pro ED 5-30X56 FFP MOA. I am pretty darn set on the scope as I wanted to keep it under $1k CAD, and its around $970-999 Cad and reviews seem awesome for the money, however I am open to different rings if theres another recommendation.
