    Good day guys.

    Can someone help me with twist rates on these rifles.
    Sako l61r 338 winmag 541xxx (1:12? Or 1:10?)
    Sako Aiii 521xxx 270 win (1:10?)
    Sako vixen 222 rem 58xxx (1:14?)

    Is there a list I can look this up like a sticky posted?

    Will the serial lookup that you pay for tell me the twist?


    Thank you

    Delko

    Should be
    338 1 in 10
    270 1 in 10
    222 1 in 14

    Can measure twist rate using cleaning rod, tight patch, and ruler. 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.
    good luck

    Would this listing be accurate for a re-barreled SAKO? Marlin's method is the only definitive one of which I am aware. Direct measurement works.
