It has a factory 1:8 tube? Tikka is usually pretty slothful about updating their twist rates, and they still show 1:10 on the website. You'd have a hard time giving me another 1:10 .243, but I don't think I could pass up a properly twisted Tikka in .243 , or especially 7mm-08 or 7mm Mag. Maybe the 7mms will get the updated twist treatment next.
