I used buckshot this year for the first time with amazing success, or maybe it just sounds amazing due to the slug "bandwagon". I shot one with a mod choke at about 60 yards, and two with full choke at 40 and 60. The only reason I had a mod in was because I was pheasant hunting the day before and forgot to switch it out. Gotta love a gun you can use for anything I would not hesitate to use it in your situation with a mod choke and 00b, all of mine dropped right on the spot!

Edit: Make sure it is legal for your area, I have no idea what your rules are, but in Pa it is illegal in most WMU's
