This refers to shotgun ammunition designed for a 12-gauge shotgun, propelled at a velocity of 1,500 feet per second. Such ammunition typically uses lighter projectiles to achieve this higher velocity compared to standard 12-gauge loads. This specific type of ammunition is commonly used in applications where increased range and flatter trajectories are desirable, such as certain types of hunting or sporting clays.
High-velocity shells offer several advantages. The increased speed translates to a flatter trajectory, minimizing the lead required for accurate shots at longer distances. This can be particularly beneficial in situations requiring quick target acquisition or when engaging moving targets. The reduced time-to-target also minimizes the effects of wind drift. Historically, the development of such ammunition has been driven by advancements in propellant and projectile technology, enabling both increased velocity and accuracy while maintaining safe pressure levels within the firearm.
