Ruger M77 Twist rate

[Rock_Steady]

Help? I have a ruger M77 made in 1976 in .250 savage. I'm having trouble with using 120 grain rounds - does anyone know the twist rate of these rifles or where I can find a chart?

TIA

Use a tight fitting (to bore) patch on your cleaning rod. Mark a starting point on the rod, when the rod makes a complete turn, make another mark. Measure the distance between the marks.
