Optimal performance with Tungsten Super Shot (TSS) in a 20-gauge shotgun requires a specialized choke tube designed to maximize pellet density and pattern efficiency at extended ranges. These choke tubes often feature tighter constrictions than standard lead shot chokes, compensating for the smaller diameter of TSS pellets and harnessing their higher density to maintain lethality at greater distances. An example would be a choke tube designed specifically for TSS loads, often marketed for turkey hunting, with constrictions ranging from extra-full to turkey extra-full.
Specialized choke tubes enhance the effectiveness of TSS loads, enabling hunters to ethically harvest game, such as turkeys, at distances previously unattainable with traditional lead shot. This extended effective range contributes to higher success rates and cleaner harvests. The development of these specialized chokes coincided with the increasing popularity and availability of TSS, reflecting an advancement in both ammunition and shotgun technology, leading to a more efficient and ethical hunting experience.
