I wanted to throw away my christensen for the first 100 rounds. Was having a hell of a time getting an acceptable group. A friend had same rifle and said keep shooting and cleaning. Low and behold about 115 rounds and damn thing is a tack driver. At 200 shoots 3/4 inch groups consistently now with hand loads. Its a 6.5 prc. Other guys i have talked to ran into same issues. Have to put rounds down in order to get them to shoot tight groups.
