RE: Is this common?
Michigan dumps nearly one million gun hunters in the woods on opening day of rifle season. With numbers like these, you bet there are people that are going straight to the woods with rifles they haven' t shot all year. It' s very common. I don' t feel it' s necessary to shoot a rifle or a bow all year - you either can shoot it or you can' t (unless we' re talking instinctive shooting - different deal altogether). By all means, drag the thing out and shoot it to make sure sights are still on, but if you' ve been shooting guns and bows all your life, how much practice does it take to be as good as you were at the end of last season? Not much. The sights are on or they' re not.
It is illegal in MI to sight in your rifle up to a week before the gun opener. People do it anyway. The day before gun being the last day of bow, is a very good day to be in the woods - people are setting up for gun running the deer all over the place.
