    That is probably because RL 17 is WAY to fast a powder in the cartridge/bullet combo. I am using RL 25 in my 7mm WSM with 180gr bullets.
    Go with the 1-9 twist.

    You can use RL17, but there may be better choices. You will only get about an 84% case fill with this powder. I use RL17 with a 130 grain E-Tip in my 270 WSM, and it works fine. You will get better performance from RL19 or RL22, I suspect. You'll get slightly more velocity, better case fill and a better pressure profile.
