Hey everyone I just bought this used 835 Mossburg Ultimag to be my new Turkey gun,anybody got any insight on what choke works well with the 3 1/2 Heavy Shot shells. Also what size gets me out to 50 yards or so with this round,4,5,6's? I think I got a good deal for 285.00 bucks or did I pay to much? Input appreaciated. I added a picture of my new Turkey gun,I've given it a name,"THUMPER" just like my old racing 4 stroke 4 wheeler back in the 80's I really like the Old School Camo look,it has some age to it like me.
