hello,
I bought an 870 Rem. 3 1/2 mag as well. I have no place to pattern the gun. I bought a box of #4 Winchester supremes3 1/2 ". I've not shot the gun yet. I will be hunting this Sat. Would you all recomend me using the normal full choke thatI bought or the turkey true glo choke.I bought as well.I'll be hunting in a swamp and my fartherest shot will be no greater than 30 yds.

Thanks from a city dweller.
