I'm not exactly sure if we're talking about the same place or not but leaving from Lockwood's Folly inlet, there are a few artificial reefs within about 5 miles. We have caught Black Sea Bass at most of these but like TA said, the bigger ones are usually a little farther out. Here are co-ordinates of a few of the close reefs.
AR-440 (Brunswick Reef) N33 49.800 W78 13.080
AR-425 ( Yaupon Reef) N33 53.060 W78 06.520
AR-420 (McGlammerys Reef) N33 51.030 W78 06.590
There is also a listing of aritficial reefs on the NCDMF web site at

Hope this helps,
