[QUOTE="Browninglover1, post: 548561, member: 29966"] I'm assuming that particular scope has the Adjustable Objective and using that correctly will make a HUGE difference. Forget the little yardage lines they have marked on it because they are usually not right. Set your gun up so that it will stay on target without you holding it and look through the scope without your head touching the stock. Move your eye up and down and side to side (again try not to hit the stock with your face) and you will see the crosshairs move all over the target. Start twisting the adjustable objective until the point that the crosshairs don't seem to move around the target as you move your eye to different positions. This will eliminate your parallax error and should tighten up your groups a lot. The first time I adjusted my parallax correctly I went from 3.5 inches of horizontal spread at 300 yards to .5 inches of horizontal spread on the very next group. If you have exactly (almost impossible) the same eye position on each and every shot the parallax adjustment wouldn't be necessary but since we tend to move our eye to a new position on every shot it seems to dramatically tighten all my groups. I do think that bedding could be a factor in your stringing, but I've found more often than not it's usually just a simple parallax error. [/QUOTE]
