Here are my two cents:
1) Why go with .308? Even if you have reloading gear for .308, it’s not that expensive to buy some for 6.5 Creedmoor or 6.5x47L etc. You will get better odds of hitting your target (there is an excellent article on precision rifle blog) and you will have lower recoil allowing you to spot your misses more easily making corrections for hits much easier. All that means that the money you spend on bullets and powder will get you more hits. If you are worried about 6.5 barrel life, there are now plenty of pre-fits and other barrel options out there. As well, 1500-2000 rounds of barrel life is several years for even an enthusiastic shooter.
2) Try as many of the rifles on your list as possible and find the one that fits you best. OR, find an action that you like but a rifle with plenty of aftermarket support so you can buy a stock that you like.
3) Decide what kind of shooting you want to do.
Personally, I’ve gone down a long road of many rifles. I started with T3s (Lite then Tactical then Custom then Sporter) then switched to a TRG (best trigger I’ve ever used) then went back to a Tikka in an XLR stock then went to a Cadex and now I’m back to a Tikka in a KRG Bravo stock. I started off shooting FTR then gradually went to PRS now only shoot PRS. For expensive guns, the TRG was beautiful and accurate but the stock didn’t fit me, didn’t have many options to customize amd has very limited aftermarket support. The Cadex was also beautiful and accurate but I found it a touch heavy and has lots of sharp angles on it which I found got in the way for PRS when shooting off barricades. Tikkas are great value / $ and I’m happy with my much less expensive Tikka / KRG setup and will be getting either a 6.5 Creedmoor or 6.5x47 barrel over the winter. Hopefully I will be done with that but you never know, tastes change and new products come out.
