Best twist for 6.5 x 47 using 123 - 130 Bullets

[Steveb]

I have been using a 1 in 8 twist Kreiger for my 6.5 x 47 L with excellent results using 123 SMK and 142 SMK's. However, I used a 1 in 8 twist in case I wanted to use 142's. These shoot very well in my rifle but it appears the bullet weight to use is the various 130's with this case capacity. Should we be using a slightly slower twist strickly for these bullets? Say a 1 in 9 twist? Anybody try a 1 in 9 or 10 using the 130 Bergers? Thanks for any information.

8.5 twist Bartlein is what I have

I'm using an 8.5tw and stabilize 139gn scenars fine. I think a 9tw will easily work with 130gn bullets.
