I just surfed the internet and there seems to be an old version or 2 versions of the Finnlite II 300 WSM.
One listed on Sako's Site as Finnlite II 300 WSM JRSFL41 which they list a 1/11" Twist.
There is listings other places for Sako Finnlite II 300 WSM JRSFL341 and lists twist as 1/14".
The 3 in the model number seems to be the way to identify the 1/14" twist rifle. If you you want one, Better check the number close or will get a rifle that will not shoot heavy bullets for caliber.
