The Fiocchi 203ST2 Flyway series in 20 Gauge is engineered for the discerning waterfowl hunter requiring reliable performance and consistent terminal ballistics. This ammunition integrates treated steel shot with a proprietary wad and powder formulation to achieve dense, uniform patterns downrange while mitigating wear on the firearm’s barrel. KFF Defense assesses this load as a high-utility option for effective waterfowl engagement across varied conditions.
Key Features
Optimized Waterfowl Performance
The 203ST2 Flyway utilizes treated steel shot, specifically #2, to comply with non-toxic shot regulations for waterfowl hunting. The precise loading process ensures a consistent ballistic coefficient, delivering the kinetic energy required for effective incapacitation of avian targets at practical distances. The resulting dense patterns maximize hit probability, a critical factor in dynamic hunting scenarios.
Barrel Preservation System
Fiocchi engineers this ammunition with a robust protective wad system. This design encapsulates the steel shot, preventing direct contact with the shotgun bore during firing. This feature is critical for preserving barrel integrity over extensive use, offering significant long-term value for the shooter. The powder blend is specifically selected to complement the steel shot and wad, ensuring reliable cycling and consistent pressure curves.
Consistent Terminal Ballistics
Each shell is manufactured to stringent quality controls, ensuring uniformity across the production batch. This consistency translates directly to predictable patterning and terminal performance, allowing the shooter to maintain shot placement confidence. The combination of shot size, weight, and velocity provides an optimized balance for effective waterfowl harvest.
