Some years ago a friend bought a used Weatherby 20 gauge o/u. He found that he could not hit targets consistently with the gun and off to the pattern board we went. His first shot was far left as was the second. I told him that he was jerking the gun and that was the cause of the left leaning pattern. He shot again with the same result and then said “you try it”. When I shot the gun the pattern was even further to the left. He ended up sending the gun to Weatherby and after several months of waiting it was returned, appropriately regulated. I was amazed at the quality of service he received on a relatively inexpensive used gun.
