A perforating gun system. The perforating gun system comprises a gun barrel housing, and a pair of tandem subs threadedly connected to the gun barrel housing at opposing ends. The perforating gun system also includes a rail. The rail defines an elongated frame having a plurality of receptacles, wherein each receptacle is configured to receive a shaped charge. A ballast is connected to each of opposing ends of the rail. Each ballast supports a bearing member which interfaces with a central bore of a respective tandem sub. In this manner, relative rotation is provided between the rail and the first and second tandem subs. A method of orienting shots in a perforating gun assembly is also provided.
