I would look at the Remington 870. If you want to turkey hunt look at the 870 Super Mag.(It can hold a 3.5" shell) It is a good gun you can pick up for around $300. It has adjustable chokes and you can buy a rifled barrel for it later if you want to. But they sell rifled slugs so I wouldn't worry about it.
Just what I was thinking.
