Yep - Bend at the waist, you will not have to aim low. You need to practice it. I'd go as far as to suggest that you hunt no more than 10 ft up until you do. If you do not, you will not have confidence in your shot, and you simply must have confidence to consistently hit where you want. Hey, look at the bright side, you missed...No bad wounding, lost deer, and you learned your lesson.

I'd also check that 30 yd pin on the range, with a hunting broadhead again.

Good luck the rest of the season
