I think this might be some the biggest Horse sh*t I have ever seen on this site. I mean after 20 yrs of bowhunting and and as many kills, I have shot one pin from 0-25 yds and I shoot a deer or target at 4 yds and then at 20 yds it hitthe same spot. I don't even give a thought when shooting, deer or target. Put the damn pin on the deer/target and shoot. All this geometry and angle stuff is just getting out of control. Now, Brett just your way and keep killing deer.
