This refers to shotgun ammunition specifically designed for 12-gauge shotguns, propelled at a velocity of 1400 feet per second. Such ammunition typically uses lighter projectiles to achieve this higher velocity compared to standard loads. This specific type might be chosen for applications where flatter trajectories and increased range are desirable.
High-velocity shells offer advantages in certain shooting disciplines like sporting clays or hunting fast-moving birds. The increased speed translates to less lead required for moving targets and a greater effective range. Historically, advancements in propellant technology have allowed for the development of increasingly faster loads, improving accuracy and performance. The availability of such specialized ammunition provides shooters with more choices tailored to specific needs and preferences.
