I've got an Remington 870 Express with a slug barrel. I'm needing to buy a barrel for Turkey hunting. I don't know much about the different barrels, so be specific as to what I should get. Is it possible to get a barrel that I can use for Turkey hunting and maybe rabbit hunting or should I just get one made specifically for Turkey hunting?I do know if I got something that is dual purpose, I would have to add a choke. Thanks for the help.
