12G Dark Storm Game with Quad Seal

Ultimate performance game

NEW for 2020. For the discerning game shooter who demands the very best, Gamebore’s Quad Seal is the most ground-breaking development in modern cartridge manufacturing history.

Taking the legendary performance of Dark Storm Game even further, the Quad Seal technology delivers never seen before knock-down power where it matters most; down range.

Designed and developed in house by Gamebore, exclusively for Gamebore, gives improved ballistic consistency, noticeably reduced recoil and increased striking energy. Plus it is fully degradable and 100% environmentally friendly, working alongside and perfectly complementing the fibre wad.

Combined with precision made Diamond lead shot and Gamebore’s exclusively blended powders, the Dark Storm with Quad Seal takes the renowned Black Gold range to the next level and beyond.
