The twist rate of the Sako L461 Vixen in .222 Remington is typically 1:14 inches. This means the rifle's barrel will make one complete revolution every 14 inches of travel along the barrel. This twist rate is designed to stabilize the lighter bullets commonly used in the .222 cartridge, ensuring better accuracy and performance. Always refer to the specific manufacturer's specifications for the exact model in question.
The Sako L461 rifle was manufactured primarily between 1961 and the early 1980s. It was produced by the Finnish firearms manufacturer Sako and has become a popular choice among hunters and sport shooters. The specific year of manufacture for an individual L461 can often be determined by its serial number.
I have a sako L461 serial no 97578. This was purchased in 1968 , so, I guess no 86302 would be somewhat older.
