My groups at 20 and 30 yards are really good. When I push it out to 40 they start to spread out a bit, and 50 is just embarrassing. I've been shooting for about a month now, and feel I should be a better shot by this point. I've identified my main problem area as shooting high or low. My groups at 40 start out OK, I usually can hit the tape (about a two inch orange square) on the first 3, then the next 3 start to wander. What are some habits that you guys do to keep your accuracy in check?
