Mesa built one for me in 6.5PRC with a 22 inch Proof CF Sendero light. First 5 shot group with it, using Hornady factory Match ammo was .43MOA, including the cold barrel shot and with a TBAC Ultra 7 on it. Mine was a similar set up but with a Ti short action, and they accommodated some personal preferences for a different brake (to make swapping the silencer faster/easier) and we eliminated the rail using Hawkins low rings. They put my March 3-24x42 on top. I've never had such light rifle. Oh, and they made it in 4 weeks. First game animal with it was an aoudad at 320 yards, taken from my knees with the support of a Spartan Sentinel tripod. I could not be happier with the whole project, including the time they spent answering my questions up front and all the modifications we discussed. They even took me to the range to help get me sighted in and gather data. John and Chad are first rate, and they are building as good an ultralight hunting rifle as can be had at any price. Others makers promote out of the box 1000 yard systems, and this rifle is every bit as good. With 5 shots to gather data at the 100 yard range, we then went to the longer range and made first round impacts at 400, 600, 800 on 12 inch plates, and then at 1000 on a full ipsc, all taken laying prone with a Javelin bipod and a sweatshirt for a rear rest. I was worried that a lightweight rifle would mean less precision at long range - but I don't worry about that anymore.
