Jaeger19, I have the Carbon Extreme in 300WSM, I purchased it right around the time I really started getting into long range shooting. The gun has a removable brake and thread protector, and the carbon fiber stock, I replaced the stock trigger with a Jewel. It shoots my handloaded 165 swift scirocco's into 5 shot, 1/2 groups @100yds when I really hold it down.
Around the same time, a friend of mine purchased the Classic in 300 RUM, with much poorer results, he never approached 1" groups, and had a couple other shooters try too also. All of them are accomplished long range shooters. After too much back and forth with the company, I believe he got his money back, but it took much effort and I think a visit to the companies plant.
So, there you have more two sided info on them. I think I got lucky, and I really do appreciate the gun for pack hunts. Even though the Extreme I have and the Classic in the 338 Lapua are two different animals, I am pretty sure that Lapua will be a handful on the bench, which makes it tougher to see just how well it shoots.
JMHO
