12G Dark Storm Steel 3" Shotgun Cartridge
High Performance 3" Precision Steel with Bio-Wad
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 high-performance steel cartridges for guns with the appropriate Fleur de Lys proof marks.
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: 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.

Find out more"For Guns who are sceptical about using steel we have no hesitation recommending and endorsing Dark Storm Precision Steel Bio Wad 3’s. They are hugely effective on our high birds. We have shot over 80 days with the majority of our Guns using steel since September and with one exception, all have been thrilled with the results! Most Guns have converted to using steel on other shoots, not just at Warter. Well done Gamebore on a super product."
