friend was varmint hunting 20 years ago and was using a low powered scope on a 22-250. he kept seeing a ground hog setting up at 350-400yards and everytime he would get ready to shoot the hog would go back down and out of sight. after 15-20 min a guy stood up right where he had been watching what he thought was a groundhog,he had been seeing the back of the guys head raise up and down as he trout fished the stream behind the field, pretty much broke him using low powered scopes. get a higher powered scope and see what you are shooting at instead of what you think you see. yes I called him stupid a thousand times after that.
