I am having a hard time shooting consistent groups with my 10 lb 338 lapua . I can shoot good on bags on the bench if I really put my shoulder into it and try to control it. Prone is another story , I just installed an atlas bipod to try and take advantage of the aft movement, I just feel like it's still blowing off target too much under recoil. I love my 6.5 cm!! I know if I struggle at the range I will have no hope in the field.
