Building on our ultimate performance Quad Seal design, the Bio-Wad Gen II is a new full cup wad utilising the same 100% environmentally safe, cutting-edge material. 

Manufactured in-house by Gamebore, the Bio-Wad takes all the benefits of the Quad Seal technology with its incredible gas seal allowing Gamebore’s exclusively blended powders to burn cleanly for maximum pressure, and incorporates a new and unique cup section for steel shot.

The Dark Storm Precision Steel with Bio-Wad cartridges have a high-tech design featuring four petals with unique 45 degree overlapping edges for complete barrel protection on pellet setback, plus ribbing for reduced surface friction and extra overall barrel protection. 

The high strength of the Bio-Wad material means we can load not only standard steel loads but also high-performance steel cartridges for guns with the appropriate Fleur de Lys proof marks.

Our precision steel shot is manufactured to ensure absolute consistency of size and sphericity and produces a non toxic alternative to lead shot with no compromise on results. 

Dark Storm Precision Steel is loaded with our exclusive Alliant double-base powder to give outstanding downrange energy and all-weather performance meaning you won’t miss using your usual lead shot. 

The Bio-Wad is now in brown to minimise visual impact in the field throughout the biodegradation period. 

Shotgun proof and choke recommendations for each load:

• 5/32gms Standard Nitro Proof Modern Shotgun. Half choke maximum.
• 4/32gms Standard Nitro Proof Modern Shotgun. Half choke maximum.
• 3/32gms *High Performance Steel Proof Shotgun with Fleur de Lys stamp. CIP regulations state no choke restriction however we strongly advise Half Choke Maximum.
  
  *Steel MPS Velocity calculated at Muzzle and falls within MAXIMUM CIP Momentum.

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