The problem is the first 5+ shots are more like a pattern then a group, after the barrel get some heat in it the group falls right in to about .4 at 100. which is fine for me as yotes are what i am after. Thanks for any and all the help.
P.S great web site full of great stuff!
I have worked on a few Christensen Arms guns that were like that. Wouldn't shoot a cold bore group to be proud of but started to shoot better once the barrel warmed.
Have you tried loading them a bit hotter?
