I have a pellet gun, and when i was hunting (my scope was calibrated when i was hunting), the gun slipped out of my hand. It didn't fall to hard, just a bump, but i decided to make sure it was still calibrated. i was shooting a piece of cardboard 10 yards away, and my gun was about a foot high, and a foot to the left. I tried adjusting the vertical and horizontal adjustment knobs (to recalibrate the scope), but they maxed out. My gun is currently shooting about 4-5 inches high, and 3-4 inches to the left. There was no wind when i was shooting to recalibrate. How could i fix my scope? I bought it at Cabelas. Would they fix it for me inexpensively? Please help.
