Same thing with me. I shoot quite often few thousands shots a months. Recently I tried to get a close group of ten shots at 100 meters and hardly could make a circle about 150 mm. At the same time and the same distance I easily hit 9 of 10 aerosol paint balloons, putting bottom to me (60 mm diameter). Don’t care about it and just shoot for my pleasure not for results. Much better shoot for crows
