Optimal constriction within a 20-gauge shotgun barrel, designed for improved performance with Tungsten Super Shot (TSS) loads, is a critical component for achieving tight patterns and maximizing effectiveness. This specialized component influences shot spread and density, crucial factors for achieving clean kills, particularly in turkey hunting and other applications requiring dense patterns at longer ranges.
Selecting an appropriate choke tube profoundly impacts ballistic performance with TSS. Historically, lead shot dominated the market, but the higher density of TSS allows for smaller shot sizes while maintaining energy downrange. This efficiency demands specialized choke tubes designed to handle the unique properties of TSS, preventing fliers and maximizing pattern density for ethical and effective harvests. The transition to TSS and matching choke tubes has significantly improved long-range performance in smaller gauges.
