Gamebore Black Gold 12ga 28gm #7.5 2 3/4” Slab

The Gamebore Black Gold Dark Storm 12ga 28gm #7.5 2 3/4” shotgun cartridge is engineered for competitive clay target shooting, specifically excelling in long-range sporting clays and FITASC disciplines. Developed in collaboration with world champion George Digweed, this cartridge delivers high muzzle velocity and features precision-graded lead shot, ensuring dense patterns even at extreme distances.

• High-Density Hull & Head: Features a 12 gauge, 2 3/4-inch (70mm) high-density polymer hull and a 20mm nickel-plated brass head, ensuring reliable ejection and consistent performance.
• Precision Diamond Shot: Loaded with 28 grams of #7.5 (2.4mm) Diamond Shot, Gamebore’s proprietary UK-made lead shot. This shot is graded five times and polished for exceptional uniform sphericity, contributing to superior patterns.
• Optimised Muzzle Velocity: Achieves a muzzle velocity of up to 1,550 feet per second (fps), driven by a custom-blended double-base RS propellant and a CX2000 primer for powerful and consistent shots.
• Advanced Wad System: Available with either a standard plastic competition wad or a 100% fibre wad. The fibre wad option is paired with Gamebore's biodegradable Quad Seal, a unique four-ring gas seal engineered to prevent gas blow-by, even in back-bored barrels.
• Target-Specific Engineering: Specifically designed for challenging targets such as distant, edge-on, or fast-moving sporting and FITASC clays, where conventional 28gm loads might struggle with energy and pattern density.
• Managed Recoil: Despite its 1,550 fps velocity, which is sharper than typical 1,350–1,400 fps club loads, the custom double-base powder and efficient gas-sealing wads work together to maintain manageable felt recoil throughout extended shooting sessions, such as a 100-bird shoot.

The Gamebore Black Gold Dark Storm cartridge is a premium choice for serious clay shooters seeking a competitive edge. Its advanced design and high-quality components ensure consistent performance and devastating patterns, making it ideal for challenging targets in sporting and FITASC events.
