The Tikka website shows 1:8 as the standard twist for the .260 in the T3x. Of course that magazine does present real problems when you try to load rounds over about 129 grains and even the 123 grain A-Max is over long by a few thousandths when seated to hit the lands. But with the Tikka you can use their WSM magazine and get another .07" of OAL. It's not much but it is enough to hit the lands and stay within mag confines using the aforementioned 123 and probably some other higher BC bullets in the 120-130 grain range.
For this reason I went with the tikka in 6.5 Swede 8 twist. It comes with the long action magazine and feeds like butter. 143 ELD-X touch the lands in my rifle at 3.182. Lapua brass is a plus and reasonably priced for the swede. ☺
