RE: Sometimes you just have to be honest .............
Don,
Do you want to use your stick for hunting? Or for 3-D shoots? If for hunting, practice one shot groups. One shot is all you are going to get.
If you shoot one shot groups, and focus on each and every shot, I think you will find your group tightening up! And as has already been noted, determine that range where you have 100% confidence and setup your bushwhack at that range and don't shoot at anything at a greater distance.
