I have a good opportunity to shoot 20-25 yards 3-4 days a week. Shot groupes aren't looking too bad. Went to shoot from a tree stand yesterday at a friend of a friends and did horrible (I hit the target, but that's the only positive thing to say). I have a climber and no trees in my yard. Any tips on adjustments from stand vs. the ground.

I could shoot from my house or garage, but its not the same as being in a small stand. Any thoughts?
