1/12 or 1/14.
The Sako L461 Vixen in .223 caliber typically has a rate of twist of 1:12 inches. This means that the rifling makes one complete turn every 12 inches of barrel length. This twist rate is suitable for stabilizing lighter bullets commonly used in .223 cartridges.
Odds are 1 in 8
1:12 or 1:14. Stick to the very light bullets.
