[QUOTE="Lefty7mmstw, post: 879959, member: 48043"] What's your twist?? Some 7mm customs have 10" twists and are more suited to bullets in the 140-150 grain range. If you are a 9" twist or so I'd look at action bedding/ barrel floating, action screw torque, shooting technique/ bagging etc., scope repeatability, barrel crown, chamber dimensions, action squareness, and bases/rings to start with. You likely only have an issue with one of the above, so I just tossed them all out as possible reasons. Also, some barrels simply don't like certain bullets. I've had a few barrels settle down when you switch bullet brands or switch from single base to double base powder. Also work on bullet seating depth adjustments with your best loads. The last thing I'm thinking of is some barrels just don't shoot as well as they "should" no matter what you do. Even expensive barrels occasionally have this problem; I hope your barrel isn't one of them. [/QUOTE]
