I am wondering what is the best barrel twist for the 123 grain lapua screnar? I was looking and have found 1/7.5 and 1/9 twists. I am hoping to change my AR-15 A-2 into a 6.5 Grendel SPR when funds become avail. So any help would be great.
Barrel twist for 6.5 Grendel

A 9 will be border line but might give you the best accuracy. A 8.5 is the most you would need for that caliber.
