RE: Mossberg 500 vs. Remington 870
The 835 Ulti-Mag is ELITE!!!! The original 3.5" shotgun, the best 3.5" shotgun out there. That flips 3'x3' boxes flying into the air at 40 yds. That's pretty damn amazing if you ask me. My shoulder doesn't agree too well though. Something I will have to get used to. I would rather suck up the pain for this gun, that be a wuss and get a gun no where near this good.
I haven't used it wing shooting for birds. Long days walkingin the woods require a nice light gun, something a 3.5" doesn't really fit. If I hunted ducks, I bet this would be just as elite as it is with turkeys.
