If you like public, the NC Wildlife game lands map has the ability to view dove fields maintained by the State. They show up in a neon color on the map.
Perkins Game Land has some larger fields and is not far off the other side of Winston. When I lived out that way, it was common to see folks setting up decoys right off the treeline. Uwharrie to the south of you may also have a few—never been, though.
If you’d like to shoot on private land and have not already obtained a farmer’s permission, you can look online for hunting preserves near you. You can typically get a peg on a dove field with a phone call.
