So far, so good. It's a beautiful rifle and is very well made. Fit and finish are excellent and the whole thing is great quality. Two issues that I noticed were that the trigger would not adjust to under 4.5lbs, but that's a CYA by Remington and is easily overcome. (YouTube) The trigger is nice and crisp at 2.25lbs now. The other issue was that the brake is not indexed exactly to the horizontal, but it turns out that is intentional. It compensates for the torque of the 300 grain bullets spinning down the barrel.
Function during break in was flawless and after cleaning, oiling and a little gun grease in the right places and the action is very smooth. I have only shot three rounds for accuracy and had to stop because they were overpressure, but those three rounds were sub minute. I'll update as I develop the load.
