I currently have a .338 Lapua with a 27" Shilen Select Match Grade barrel and 1/10 Twist.
The chamber needs to be re-cut, and I am also looking at shortening the barrel significantly to help with stiffness & timing.
Does anyone know if I can trim this down to a 20" barrel & still get away with the 1/10 Twist?
I know I will be loosing a few FPS due to powder burn, but stiffness & accuracy are my main concerns.
