Did you try slackening the barrel hinge bolt a tad Mort . It sounds crazy to me too but apparantely an overly tightened barrel bolt can cause issues with scope accuracy on the ball lock up on these 30’s . If it was me I think I’d go the diopter route if loosening the barrel doesn’t work .It’ll definitely prove a little more challenging over the range your shooting .
