RE: 870 Express Super Magnum
You already got good advice. I have an older 870 that is full camo and a 20" barrel. I like it alot. But I have never shot it at a bird. It patterns nice though. Now if I can just get a bird to cooperate. LOL
Seriously, I realy like the 870. My deer gun is an 870 and is the most acurate slug gun I have seen. 125-150 is not out of the question and even beyond that too. But the mossberg is a great gun too.
Just get what feels the best in hand and go from there. As for the camo...I like camo but many turkey have died in front of a non-camoed gun.
If I were looking though I would serously consider a thumbhole stock or pistolgrip. Those feel NICE.
