This rifle did have issues, it was sent back to christensen. It was grouping horribly. They replaced the barrel and bolt, the issue seems to have been resolved, I did shoot it. I have not yet found which ammo this gun likes in particular, as i have already moved on and replaced the gun with something else, so i am selling this one.
