[QUOTE="mgerulat, post: 525102, member: 35082"] I've posted this response on a few other similar threads, bottom line is that "generally" Chrsitensen Arms (CA), group poorly, its the carbon barrel. We have done a number of experiements with them and the bottom line is the barrels have major issues with resonance or whip, its the way the carbon fiber is mated to the barrel liner is one problem. The other is they take a shilen blank and turn it down too far and too fast ruining the barrel tolerances, and they don't use the select match grade of barrel on the custom seires but the cheaper match grade. I've had a number of them, and none have shot consistantly over time and temperature. Some have shot like a 1/3 MOA, but the next time you take them out with the same load and conditions they'll shoot 2 MOA! All of them have had tight necks in the bore, We've tried lapping them, mating them to custom actions, recutting crowns and nothing gets them to shoot well. Another problem is the barrels will move with temperature, 1st group shoots dead on the target area, next group shoots 2 inches to the left etc. This is due to outside of the barrel sleeves not being concentric with the bore. We take them on trade all the time for our custom rifles. Our high velocity custom rifles shoot near one hole groups consistantly over temperature always, the CA's never do.
