I went to cabela's and tried all the tikka models and for me all models were comfortable. One thing common that I noticed in all of them, the action it is so damn smooth. I chose my brand and I chose my caliber the only thing is which one should I grab from all those models with that budget. Just wanna make it clear one more time I'm willing to pay $1500 just for the rifle itself.
Harry, if you've chosen the Tikka, good choice IMHO.
I prefer the 30-06 over the 308Win, for lots of good reasons, most because you can shoot bullets heavier than 165 grains FASTER and they are available as factory-loaded ammo.
You might want to consider a different cartridge, but if I were you, I would stick to the something that you're sure will be available, no matter where you shop.
Most gun shops will have a decent selection of most common cartridges, in several brands, and grades.
Both the 308 and 30-06 are included.
There are other good cartridges with the same advantage, but once you get to out of the way areas, choices are limited, sometimes extremely limited to three or four cartridges, depending on which the store owner shoots.
The 308Win has the advantage of being able to buy bulk surplus ammunition, which is all Chinese these days, but the odd lot of European stuff comes available from time to time. The war in Ukraine is gobbling most of it up these days.
