12G Black Gold Game UER Shotgun Cartridge

The latest addition to Gamebore’s Powerhouse Division; Black Gold Game UER.

Incorporating the most technologically advanced components we’ve ever developed – Our R&D team have worked tirelessly to improve upon our original Black Gold Game loads, carefully dissecting and analysing every last detail to identify qualities that could be enhanced further still, accomplishing a level of performance never achieved before.

Our aim? To maximise downrange speed and effectiveness without excessive pressures and recoil.

The density of our full-cup next generation Bio-Wad allows it to travel even further with the shot still enclosed. It is 2.5x heavier than the equivalent plastic wad, resulting in a prolonged drop-off point, creating tighter patterns at extended range. Its flexible crush zone generates improved shock absorption to reduce the impact on the shoulder, allowing you to shoot for longer, experiencing less fatigue.  

The next generation Bio-Wad incorporates Quad Seal technology – our exclusive, four-ring gas seal for improved overall ballistic consistency, reduced recoil and increased striking energy. 

Now used in all Black Gold UER produced for the 2026 Game Season and onwards: The next generation Bio-Wad builds upon our commitment to environmentally responsible shooting, delivering the same 100% biodegradable performance with an enhanced shooting experience. The improved Bio-Wad material biodegrades naturally over a longer period, similar to a traditional fibre wad, while leaving barrels noticeably cleaner after use, combining sustainability with improved in-field performance.

Advancing the Lead pellet yet another level, with added antimony and graded even further than our renowned Diamond Shot in our purpose built, on-site grading facility. Diamond Shot Xtra is British lead, processed, perfected and refined here at Gamebore to produce the optimum in both sphericity and aero-dynamicity, in every pellet.

Our custom blended double base RS Propellant gives the highest performance possible, whilst remaining comfortable for the shooter.

Storage: All cartridges should be stored at room temperature in a dry location. Adverse temperatures may affect performance. Do not expose to extreme temperatures.

Specialist Cleaning Instructions for Pre-2026 stock: Using a bronze wire brush, remove the excess wad residue whilst dry. Next, spray a mild, water-based household cleaning product such as glass cleaner down the barrels and leave for a few minutes to allow the breakdown of any stubborn residue. Use the bronze wire brush again to remove any remaining streaks, followed by a rag or dry tissue to wipe away the remaining cleaning product. Dry the barrels thoroughly before applying a gun oil.

As with any type of cartridge; barrels and chokes should be cleaned after each use to avoid buildup of residue.
