Not that it really matters but curiosity has got me. I purchased a T3 stainless in .260Rem this summer, and when I bought it Tikka's web sight said the twist was 1in9. I debated buying a Sako85 because the twist was 1in8 and all the 140 gr bullets recommend 1in8 twist. Now on Tikka's web it says it is a 1in8. So is mine a 1in9 or 1in8. Like I said not that it matters, it shoots all the 140 grain bullets that I feed it very well, I was just wondering. Maybe it was a misprint before?
Tikka question.

Good ideas. The barrel is not stamped and the manual says 1in9. I wonder when they switched. I was under the impression that they just started making the 260, I phoned and e-mailed over 50 dealers across Canada and got one the first ones to land here. Makes me wonder if they had a misprint in their literature and just fixed it. Also they are the same company as Sako and the Sako 260 is 1in8 and the 6.5 swede in Tikka is 1in8, you would think they would use the same barrel blanks.
Measuring the rifling twist rate in a rifle barrel.
To measure the twist of a barrel, use a cleaning rod, magic marker and a tight patch.
1. Make a straight line with the magic marker the length of your cleaning rod.
2. Start the patch down the barrel, stop and mark the rod at the muzzle and a mark on the muzzle.
3. Push in the rod slowly until it has made one revolution, this is verified when the line on the rod lines up with the mark on the muzzle, then make a second mark on the rod at the muzzle.
4. The distance between marks on the rod is the rifling twist rate in your barrel.

No it doesn't matter as I stated that before, I was just curious. I checked it the way Blargon sugested and it is indeed 1in9. Still shoots 140's to an average of .65 with my smallest 3 shot groups at .31 and .36. Good enough for a hunting gun. Just curious why they would change it from a 1in9 twist to a 1in8 twist after a a year or so.
Thanks again all.

I am thinking they might have changed it because that's what the Sako's are built as, and as such would be way more economical to just make them all the same, rather than have one with a different twist rate..if in doubt, it's usually about money.
My opinion is that they didn't want the 260 Rem to compete with the Swede, what a grain of bullet is most commomly loaded for 260 Rem as a factory round 140? I think the Swede has the 1-8 for heavier than 140 gr, then decicided to have one twist rate for the 6.5 caliber much easier in a factory, plus they may have had a lot customers who wanted the 260 Rem in 1-8 twist, just my thoughts
I know what you are saying, I was going to buy the same gun, one year 1-9 next year 1-8, you think your buying a 1-8 and you get a 1-9???
