I finally figured out how to put different guns in Chairgun but have encountered an issue. When switching from one gun to another, all the info changes to that gun except the maximum yardage. Example, my Marauder has a max of 55 yards and my 1720T has a max of 30 yards. If I go from the Marauder to the 1720T, max yardage changes to 55 yards on the 1720T. If I change the 1720T to 30 yards and go back to the Marauder, the max changes to 30 yards on the Marauder. Any idea what I'm doing wrong. Thanks, Don
