Twist for 243AI

[Rupe]

Going to rebarrel a Striker to 243 AI and was wondering what twist I should get for bullets from 60 to 100 grains ? Appreciate it.

I personally shoot a nine twist and 107 Sierras and they work great. I'm sure you could use the 10 twist if you don't shoot over 100 Gr. bullets but my nine twist shoots the 68 Gr. Berger FB bullets and the 90 Gr. Berger BT match bullets lights out.

I have a 1 in 8 and to shoot 70 to 115.
