I own a Mossberg 835 Ulti Mag 12 guage, 28 inch barrel, all camo gun, and use it for everything I hunt, including turkeys. I have never had any problems with this gun like some of you all are saying. It is an outstanding performing gun, and stands up to some very rugged use. I hunt a lot in the swamps of Louisiana, and it handles everything I can give it and in return, I take very good care of it.
I have four different chokes for this gun, and my turkey choke is a comp n choke tube, and it gets out there and reaches. When shooting the 3.5 inch magnum shells, ducks, geese, hogs and turkeys just dont have a chance at far ranges cause it gets out there and smokes them. For smaller game I change my choke to mod, or regular full and shoot either the 2 3/4 inch or the 3 inch. I even have a rare IC choke tube which I never used yet but I guess one day I will hunt something to use it with.
For me it is the best performing gun I would ever want, and trust me I have used a lot of guns. It never fails no matter what shells I use, or how fast I pump it, so I just had to give you all my opinion.
