I have taken plenty of deer with buckshot out to 60 yards. I am using a full choke mossberg with 3" 00 buck. Most have been less than 45 yards, 2 have been at 60. I prefer my 30-06 but some of the places I hunt are pretty thick swamp bottoms. I would pattern the shotgun with a couple different loads so you will know what to expect. Mine will hold a winchester round out to 65 yards, but a remington 00 only patterns good out to 45 yards for me.
