So I have a lane in my yard I can set up a target in, but near the end it slopes downhill. So at about 10 yards I’ll be shooting slightly downhill at it. From about 30 yards out it’s mostly level, then the drop. Any ideas how this will change sighting in at 10/20/30? Also since I’m practicing for shooting out of an elevated tree stand, will this screw me up in a big way?
