I get out at least twice a week the whole summer. When hunting season got closer this year I switched to shooting broadheads one at a time. I have a poor-man's 3d target (a paper deer target taped to a broadhead block target). I set it up and then shoot at it from different angles, body positions, distances, and elevations (I shoot in a field with some hills about 6-10 feet higher than the target.) I try to never take the same shot twice.
I also try to practice drawing really slowly, like I would when taking a shot at a wary deer. It's much harder to make sure I fully expand when doing this, so I force myself to do it properly. My problem has always been shooting under the deer because of shortened draw. Not this season!
