A spear gun and a power load for use therewith, the spear gun including a breech, a barrel fixed to the breech, and a spear adapted to be received by a bore within the barrel. The breech includes a chamber for receiving an explosive power load, the chamber being in fluid communication with the bore. The spear is sized to substantially prevent the flow of gas between the spear and the bore and may include a gas restrictor proximate one end to further reduce the flow of gas past the spear. The power load has no projectile and includes an explosive sealed to prevent water damage to the explosive. A line retainer adapted to be carried by the spear includes a plurality of pins urged toward the spear, the pins being adapted to be received in a reduced portion of the spear.
