Best twist rate

[leopard6.5]

Zach: I can't find where Bill A. said this in going through his posts.

I did find him saying this: " 1 in 7.5, 7 will run at 10" but 9 is for 20" and up"

Where did you see him say to use the 1-in-7.5 for the 20"-18" barrels?

When he said to use 1-in-7.5 he was saying this in reference to a 14" barrel and then 1-in-7 for a 10" barrel.

Thanks for the clarification.
