I picked up a Mossy 590A1 for July 4th and have been loving it. I've done several range sessions with different magnum buckshot, reduced recoil buckshot, and different slugs (with some birdshot thrown in). Gosh I love that gun, it has a Bantam stock which is a tad smaller and an 18.5" barrel (the thing feels really small even with no pistol grip; and shoots like a dream). I'm about to invest in a comp or copstock from Knox because defense loads are pretty vicious in this thing. I love the A1 because the heavier barrel and trigger guard make you feel like you could beat someone to death with it. I haven't had a chance to test it on any clay pigeons but I'm sure I could dispatch some if I pick them up right out of the launcher.
