Twist rate

[Mr.Snerdly]

Are there numbers or markings on my 22-250 Model 12 to determine the twist rate?

Do a search for "twist rate code" . I think you may find your answer.

[GaCop]

I think you'll find it probably one in twelve.

[Dave Hoback]

It’s either 1:9 or 1:12. If you give use the exact model you have we can tell you. Or, simply search as mnbogboy2 pointed out.

But No, there are no markings indicating the twist rate on your rifle.

Easy to figure if you have the barrel. Put snug patch on cleaning jag & rod, mark rod so you can see it rotate. Push rod one revolution, measure distance rod moved.

The 12FVs are 1:12 as far as I know. Mine is.
