12G Dark Storm Multi-Shot Steel Shotgun Ammo
The Ultimate Ammunition for waterfowl
Designed for the demanding North American waterfowlers, Dark Storm Multi-Shot Steel
Delivering uncompromising performance when weather, distance, and birds are at their toughest. Intelligent multi-shot engineering, precision non-toxic materials, and full cartridge waterproofing combine to produce devastating performance with consistent patterns and serious downrange energy.
Multi-Shot Payload (2/4 Configuration)
A precision-stacked shot column engineered for maximum effectiveness. Larger #2 shot leads the payload to arrive first on target, delivering deep penetration and retained energy at longer ranges. Trailing #4 shot follows to tighten patterns, increase pellet density, and dramatically improve kill probability on closer birds.
Zinc-Plated Steel Shot
Premium zinc-plated steel shot resists corrosion and surface degradation, ensuring consistent ballistics ans reliable performance in wet, salt-air, and sub-freezing environments.
Locked-Out Waterproof Technology
Advanced waterproofing seals the cartridge from primer to crimp, protecting the powder charge and shot column from moisture intrusion - even after prolonged exposure to rain, snow, or flooded blinds.
Temperature-Stable Double-Base Propellant
High-performance, double-base powder delivers reliable ignition, consistent velocities, and uniform pressures across extreme temerature swings.
1450 FPS Optimized Velocity
Tuned to 1450 fps - the proven sweet spot for steel-shot performance, delivering the ideal balance of tight patterns and downrange energy.

Technology
Alliant Powder
Exclusive to Gamebore in Europe. High technology, cutting edge double base (nitroglycerin) powders allow us to develop and manufacture high performance loads without excessive perceived recoil. Alliant powders feature in our small gauge loads, high performance heavy weights, premium steel and non toxic cartridges. These loads simply cannot be replicated by using single based propellant.
Nickel Head
Nickel plated heads to give smooth, consistent and reliable ejection in higher performance loads.
3" Hull
A 3" (76mm) hull for use in guns with 3" chambers where case length is critical for optimum performance.
Gamebore Wad System
Plastic wads manufactured in house to our unique designs and exacting standards. Giving consistent performance and delivering perfect patterns every time, using the very latest manufacturing equipment and the best materials available.
D 7.9
Shot with a Density of 7.9 gram/cm3
Extended Range
Muzzle velocity is only part of the story - downrange energy is key to a cartridge's long range effectiveness. These cartridges are designed to deliver unsurpassed performance downrange where it matters most, giving knockdown performance others simply cannot match.
Ultimate Performance
Developed to ensure each component combines to give their maximum potential and deliver results which are greater than the sum of their parts - simply the cutting edge of performance cartridges.
High Velocity
Cartridges with high velocity are ideal for performance use and demanding disciplines where targets are at range.
Precision Plated Steel Shot
Zinc plated for corrosion resistance, precision uniform size for consistent pattern and penetration.
Locked Out Technology
Advanced waterproofing seals the cartridge from primer to crimp, protecting the powder charge and shot column from moisture intrusion - even after prolonged exposure to rain, snow, or flooded blinds.
