I have one in a 338 Win Mag. It is a great gun. The stock isn't awesome, but does the job fine. I bought my gun right as they came out with the accustock, so mine is a pre-accustock model. I use Barnes TSX bullets and get about 5/8" groups at 100, and everything on the gun is stock. The accutrigger is a great crisp clean trigger.
Overall a terrific gun, especially for the price point.
