+1 Even a 1 in 12 will work if you are going to load hard.
I have a 1 in 15 on mine and it shoots the 60 to 70 grain bullets well. It was built for the 35
to 40 grain bullets @ 4400+ but does good with the bigger bullets because of the velocity.
Go with the 1 in 10 and if you want to shoot 40 grain bullets use the 40 grain Ballistic tip
(Because it is very tough and will hold together).
The 1 in 8 or 1 in 7 are good in the 223 Rem with the biggest bullets because the velocity is
way down from the 223 WSM.
