I finally got to take my new 5.5 in 22 cal single six to the indoor range for sighting in. I started at 5 yards and right away was shooting 3 inches too high. After numerous adjustments and different ammo the best I could do was 1 to 1.5 inches too high with the rear sight maxed out. Anyone have any ideas on what to do next? By the way the gun was giving me some impressive groups with cci mini mags at 10-15 yards. Starting to really like this gun. I just need to get my elevation in check. Thanks
