I have been shooting long range for over a year and every gun that I shoot off a bipod jumps to the left on the shot. I have tried a lot. Different load pressure, different body angles, different bipod. No matter what on all shots the rifle settles to the left. On my 5r milspec it's about 1.5 mil. On my tikka hunter 6.5x55, about 2.5. What should I do or try to fix the problem? Or am I just asking for too much and this is acceptable?
