I've not shot any of it but vintage gun shooting friends have confirmed what some of the other boys are saying, that it's pathetic as far as duck killing. A friend bought a case of the 2 3/4 20 gauge to use out of a Remington Model 11 and it was so low power it wouldn't even work the action with the rings on the light setting. He shot it on two different days out of another gun and said that what few birds he did knock down needed three or four cripple shots and he lost several.
I'm with 12brd, spend the extra money on some Kent TM and you won't be disappointed. I've been shooting it almost exclusively since it came out and can't tell the difference between it and the same load in lead. This from a guy who duck hunts two or three days a week through the entire Michigan and Ontario seasons. I'm not an occasional duck hunter, I'm serious about the sport, I use it because it kills birds dead in the air.
