Has anyone used an ATA semi for Waterfowl hunting yet . I' d like to get your thoughts including what you used before . I have already bought a different brand 12 but was handling a camo 20 today . Comes with 5 chokes but only a 1 year warranty . I see a lot of their pumps getting traded back in so it makes me wonder . I hear good reviews on the sporting / trap guns . Just ATA owners please .
