This specific information refers to the specifications required for handloading ammunition using Hornady Sub-X bullets weighing 190 grains. This includes recommended powder types, powder charges (measured in grains), and expected ballistic performance metrics such as velocity and pressure. These specifications are crucial for safe and consistent ammunition production.
Accurate and reliable handloading information ensures consistent projectile performance, contributing to accuracy and predictable terminal ballistics. Safe loading practices, informed by reliable data, mitigate the risks associated with high-pressure events during firing. Historically, handloaders relied on published manuals and personal experimentation. Modern access to comprehensive load data enhances both safety and precision.
