My brother just got a yellow jacket target the other day. Well I went out w/ him to shoot and my broadheads were shooting lower than I prefer them too. Right before season I had it sighted in and was confident with it. Glad I shot today and found that out. Not really sure why it happened. I anchor same points each time, at least I think I do. Thats why its important to shoot during season, not just during the off-season.
