I LOVE my Remington 870 12 ga with fully rifled barrel. I have taken 3 deer in 4 years with the setup. With open sights at 100 yards it puts them in a paper plate until my shoulder gets sore.

With the bird barrel, the gun sees a lot of duck hunting (of course), misc. small game, trap & skeet and deer drive use. IMHO, if you' re buying a new gun, get something a little more versatile than a single shot or bolt action.
