Well i know these aren't on your list but here goes. If you want the ultimate range and most devastating gun i've seen its the Beretta Extrema 2, Carlson .675 tube using Hevi13's with 2.25oz of #5 shot. I call it the Turkey Shredder cause 60 yds and in it will totally destroy a gobblers day. It'll post an amazing 200-220 #5 Hevi 13's in a 10" circle at 40yds and all those #5's are like a freight train when they make their delivery.
However, if your looking for the lightest and most sweetest shooting gun on the market i've found none better than Benelli's M2 12 and 20 gauge. I just bought the 20 and its posting 120-130 #6 Hevi 13's and still in the early stages so think i can improve on that a bit once i find the right combo. I believe the 20 gauge with 24" barrel weighs about 5.8lbs and the 12 gauge weighs in at 7lbs. Anyway, good luck with your choice and with the 2012 turkey season.
