I have a 300 win mag
Sako IV ??
serial number 652xxx
looking for the twist rate??
You could stick a cleaning rod with a tight patch down the barrel and measure how much you have to pull the rod out to get one revolution.
Twist rate should be 1 in 11”. The method Chris mentions should help verify. Some barrels vary slightly.
