Go with : #1 Remington 870, #2 Mossburg 835 Ulti-Mag. I have both, the Rem. in 3" & the Moss. in 3 1/2". Go with a 3 1/2" ! I would also recommend a good Turkey choke, I & all my hunting buddies prefer the "Kicks Gobblin Thunder". The folks at Kicks Industries will help you pick the proper size. Also use Winchester ammo! Good Luck!
