The possible ricochets occurred Friday afternoon during training at the South Jersey Shooting Club in Winslow Township, said George Smith, the club's manager.
"None of the injuries were life-threatening, thank God," Smith told Daily Voice.
Smith said the club turned video of the shooting over to authorities.
Winslow Township police referred phone calls to the Gloucester County Sheriff's Department. The sheriff and undersheriff did not return messages for comment from Daily Voice.
