I have a Super X3 and I'm absolutely head over heels in love with it. I do clean it after each "outing" and so far I'm up to roughly 1200 rounds of 2-3/4" through it with out any trouble with it ejecting. I could talk all day about this gun, but I won't. I think you'll love it for bird hunting, as one of my favorite thing about this gun is how it shoulders and swings.
Good luck!
