I have a bushmaster predator with a Harris bipod and a Nikon 4.5x14-40. At 100 yards I can put 10 bullets almost all in the same hole about 1.5" above the bullseye. (I shoot at a paper plate with a set of cross hairs centered on the plate.) At 200 yards I can still hit the plate, but thats about it.The impacts are all over the place. I have noticed that I struggle more to keep my scope centered on the target when shooting at 200. The target is so small that I think maybe I tense up some, and maybe try too hard. Do you think I am trying to be too precise? Should I have a bigger bullseye to shoot at instead of 2 lines drawn by a sharpie? I missed a groundhog yesterday when my six year old daughter was with me and I couldnt think of any way I could blame her for it. Please give me some of your shooting tips and techniques.
