I think it's quite possible that you have a form of target panic. I have the same problem that you described and I have TP pretty bad when shooting at bullseyes. There's just something about a bullseye that blocks me from holding my pin directly on center. When I aim at a 3-D target, a leaf on a tree or the vitals of a deer, I can hold dead steady on EXACTLY where I want to aim. I'm just glad that it's not the other way around. I'd hate to have TP when shooting at deer.
