I dont know what I am doing wrong. Last year my shotgun was sighted in. I cant seem to hit my darn target. I only hit it a few times and I shot alot of rounds. Once I do hit my target my group is pretty tight. It just seems like most of my hits go somewhere I have no idea. I am shooting 50 yards away. The target paper I am shooting at is about the size of two note book papers. I aim for the center it seems most of my shoots never hit the center or even the paper. What am I doing wrong?
