I bought one of these awhile back, went out into the backyard, with standard pellets, joker sounded like a 22 magnum. I boxed it up real quick and left the house in case the cops came. Returned it to academy...I just wasn't expected that out of it. Gamo told me it would take about 300 pellets before it quieted down...which I obviously couldn't do at the house. Went back to my colibris and 22 quiets out of an old springfield/savage 120
