Optimal performance with TSS (Tungsten Super Shot) loads in a 20-gauge shotgun requires a choke tube specifically designed to handle the density and hardness of this shot type. These specialized choke tubes typically feature harder, more durable construction materials and unique internal geometries to mitigate shot deformation and maximize pattern efficiency downrange.
Selecting an appropriate choke tube is crucial for realizing the full potential of TSS loads. These dense pellets retain energy and velocity over longer distances, leading to improved lethality and effective range compared to traditional lead or steel shot. A correctly matched choke tube ensures tight, consistent patterns, minimizing pellet deformation and maximizing energy transfer upon impact. This is particularly important for hunters pursuing small game and waterfowl where precise shot placement is critical.
