The practice of firing steel shot through a shotgun barrel with a tight constriction, known as a full choke, is a subject of concern among shooting enthusiasts. Full chokes are designed to produce a dense, tight shot pattern at longer ranges, typically with lead shot. However, steel shot’s properties differ significantly from lead; it is harder and less malleable. This difference leads to potential issues when forcing steel shot through a full choke.
The significance of this matter lies in the potential for damage to the shotgun barrel. The harder steel shot, when compressed by the full choke, can create excessive pressure and friction. This pressure can result in barrel bulging, ring formation, or even catastrophic barrel failure. Historically, lead shot was the standard, but environmental concerns led to the increased use of steel shot, necessitating a reevaluation of choke compatibility.
