I had my savage on my coffee table the other day and it has a burris 6.5-20x50 tactical scope on it. It was zeroed and just shot it the other day and it was perfect. i bumped it and it rolled off and the rifle fell maybe a foot onto the carpet. i was worried so i went out and shot it at paper and it was now hitting about 5in high and 3in to the left. would a little fall like that be enough for a nice scope like that loose its zero so easily?
