My opinion, and that's all it is, save your money and buy the Remington if you like it. I've hunted ducks since age 14, must mean last season was my 39th. I've always used cheap pumps. Why? Am I just cheap? Am I stricken in poverty? No, it's just that salt marshes and duck hunting (especially out of boats) is hard on a shotgun. An, pumps do the job well. I made a beautiful Spanish double into a beat up ugly utility gun hunting ducks and geese with it in salt marshes.
You don't need heavy shot, ten gauges, what not for shooting ducks over decoys. Steel number 4s in 3" 12 do the job just fine. You DO need heavy shot for geese, decoys or no. They're tough birds and die hard especially at long range.
The Remington 11/87 is as good a gun as any for ducks. Tell me what the Benelli can do better so I can get a good laugh.
The Benelli is just bling, showing off ones wealth, or to people who know better, stupidity. JMHO, though. I'm a utilitarian kinda guy. Now, I love a fine shotgun (doubles please) as good as the next, but I'll never tear one up duck hunting with it again.
Barrel length, 28" preferred.
Is a camo version the way to go?
I find the camo seems to hide better, really. It's not worth arguing about, though. However, it does hide the rust that will eventually form on the gun if you come hunt down here with me on the coast. My Mossy has seen 15 years or so now and it has a couple of rust spots that you have to look close to notice. Main thing, get the plastic stocks. Stocks catch heck on nails sticking out of blinds, banging around in boats, and such. If it came with nice walnut, take it off and buy some plastic to use with it in the marshes.
