The Difference Between Bio-Wad and Bio-Wad Rapid
Learn how the Gamebore next generation Bio-Wad and the Bio-Wad Rapid deliver exceptional shooting performance with fully biodegradable wad technology.
Understanding the Difference Between Gamebore Bio-Wad and Bio-Wad Rapid
As the shooting industry continues to evolve towards more environmentally responsible solutions, shooters are increasingly looking for cartridges that deliver outstanding performance without compromising on sustainability. At Gamebore, we recognised early on that “green” products should never mean sacrificing quality, consistency or protection for your gun.
That philosophy led to the development of two advanced biodegradable wad systems: Bio-Wad and Bio-Wad Rapid.
Both are designed, developed and injection-moulded exclusively by Gamebore at our manufacturing facility, and both feature the same ultra-technical design characteristics engineered to deliver exceptional performance in the field.
So what’s the difference between them?
Engineered for Performance
Both the Bio-Wad and Bio-Wad Rapid are full cup wads designed to completely enclose the shot load, offering maximum barrel protection, particularly important when shooting steel shot.
Each wad incorporates Gamebore’s advanced Quad Seal technology, creating a highly efficient gas seal for improved consistency, velocity and pattern performance.
The precision injection-moulded petals are cut at exact 45-degree angles, specifically engineered to prevent pellets from protruding through the wad and contacting the barrel walls. This dramatically reduces the risk of barrel damage associated with steel shot.
For additional protection, the wad petals are ribbed, increasing the separation between the shot and the barrel. Combined with the material density of the wad itself, this allows the shot to remain enclosed for longer during flight.
The result is tighter, more controlled patterns at extended range.
In fact, both Bio-Wad variants are approximately 2.5 times heavier than an equivalent plastic wad. This increased mass creates a prolonged drop-off point, helping maintain shot containment for longer and enhancing long-range pattern efficiency.
Both designs also feature a flexible crush zone that improves shock absorption during firing. This reduces felt recoil and shoulder fatigue, allowing shooters to remain comfortable during longer days in the field.
Fully Biodegradable Without Industrial Composting
Unlike some biodegradable wads currently on the market, both Gamebore Bio-Wad systems are made from materials that naturally biodegrade in the open environment and do not require industrial composting facilities.
Both products are 100% environmentally friendly and designed to reduce visual and environmental impact in the field, while still delivering the premium performance expected from a Gamebore cartridge.
Bio-Wad: New for 2026 - Cleaner Barrels, Proven Sustainability
The next generation Bio-Wad is designed to biodegrade naturally over a longer period, similar to a traditional fibre wad.
Because the material is not water-soluble, it leaves shotgun barrels noticeably cleaner after use, reducing residue build-up while still delivering excellent environmental performance.
This makes Bio-Wad an ideal choice for shooters wanting a highly effective biodegradable solution that combines sustainability with cleaner-running in-field performance.
Bio-Wad Rapid: Fast Biodegradation in Just 30 Days
The key difference with Bio-Wad Rapid lies in its exceptionally fast biodegradation time.
The word “Rapid” refers to the speed at which the wad breaks down naturally in the field. Manufactured using an exclusive water-soluble material found only in Bio-Wad Rapid, it biodegrades in as little as 30 days.
Shooters therefore benefit from the same advanced wad engineering and performance characteristics as the standard Bio-Wad, but with significantly accelerated environmental breakdown for use at locations where landowners demand faster biodegradation.
Two Solutions. One Goal.
Whether you choose the next generation Bio-Wad or the Bio-Wad Rapid, both products are built around the same principle:
Delivering uncompromising shooting performance while reducing environmental impact.
Both wad systems offer exceptional barrel protection, advanced pattern performance, recoil reduction and true field biodegradability, giving shooters the confidence to choose the solution that best suits their shooting requirements and environmental preferences.
