Since your shots on groundhogs have all been 200 yards or less,you don't require a great deal of accuracy to make them.Even 2" to 3" groups will get the job job.However on paper 2" to 3" groups would be considered very poor by many people.I have seen people sight in rifles by shooting at stones or bottles.Yes they do hit them most of the time,but they don't even know if they hit them high,or low or to one side,or the other.Like yourself,these people do often shoot very poorly at paper targets.In reality,you may not be any more accurate when shooting objects or animals but because the targets are quite large by comparison to the bullseye on a paper target,you are made to believe that you are.
