Have a 300NM MPR that shoots well. Had a 6.5 PRC MPR that shot sub MOA as well. Neither has a really smooth action on them. I ended up selling the 6.5 PRC barreled action, keeping the carbon chassis, and will soon be putting in a Bighorn Origin w/Proof 6.5 PRC barrel. The Christensen actions just don't measure up to 'semi-custom' actions such as the origin or ARC Nucleus, and not even close to a Tikka. Shooting more of my Tikka just left me unhappy with the Christensen action and eventually made it worth my money to pay to move to the Origin + Proof barrel.
I've heard a good bit of issues with barrels from Christensen. If you get a good one, as I did on mine, they shoot well. But you can be in for some frustrating experiences and shipping back to Christensen on your dime if you get a sub-par one.
