I wonder if there is something about those Tikka/Sako barrels in 7mm-08, I know this is an old thread, but I have a Sako 85 Finnlight in 7mm-08 and I'm shocked at the 2.5 - 3" Groups after getting used to close to one hole groups with other Tikka's and Sakos that I've owned. Any further thoughts on what type of ammo might tend to shoot best out of these barrels?
