Hello, looking for any advice regarding my christensen arms 300rum. I have a consistent accuracy issue that is driving me nuts. Through out load development I have been experiencing a group pattern where 2 are sub 1/2 moa and the third is 1moa or more. I sent the the gun back and had a select match barrel installed and have experienced the same pattern. The best load in the old barrel was 210 vld 92.5 h1000 3.685 o.a.l. The new barrel likes 92.5 retumbo and a 200 gr accubond or 210 vld 3.665 and 3.685. I have achieved .490 .450 respectively but it will only shoot one out four groups. The others display the same old pattern of basically touching and a third randomly positioned somewhere out at MOA or more. There is no consistency what shot or where out side it will be. The velocity spread is low (15fps). I guess I am left scratchig my head and am quite frustrated at this point. If any one has had similar issues or I am missing something please feel free to put in 2 cents. Thanks so much for any help.
