i can tell you that my vigilante shoots 1 to 1.5 inch groups with its best pellets. biggest issue is how thick the front sight blade is... it covers a complete 1 inch circle at 10 yards. i painted it to be able to discern the space between the rear sight blades and the front sight. at 30 ft it can hit a 1 inch circle all the time. my barrel is also loose, i press it in to make sure is seated every time i load a clip in it. i am thinking to just pull it out a bit, put a dab of clear nail polish and sit it back in. that should be plenty.
