With this setup zeroed at 38yds, I can shoot a 1/2" kill zone point blank from 14-42yds. At 45 degrees I'm +/- 1/2" from 10 23yds. If they are really high up there in the tree I just aim a little low. A 45 degree shot peaks at an inch high around 40yds. I've decided it is pretty rare that I shoot at angles much greater than 45degrees.
