Understanding Ballistics Specifications Hornady Sub-X 190 S

The Hornady Sub-X 190 grain bullet is designed specifically for subsonic performance, meaning it travels at speeds below the speed of sound (approximately 1125 feet per second, depending on atmospheric conditions). This is crucial for suppressed firearms, as it eliminates the sonic boom associated with supersonic rounds, resulting in significantly reduced noise. The “S” in Sub-X 190 S likely refers to the projectile being specifically designed for Subsonic applications.

Defining Ballistics Specifications

Ballistics specifications encompass a range of data points that describe a bullet’s performance, including:

* **Bullet Weight:** Measured in grains (gr), indicating the mass of the bullet (190 grains in this case).
* **Bullet Diameter:** The width of the bullet, typically measured in inches (e.g., .308 for 300 Blackout).
* **Ballistic Coefficient (BC):** A measure of a bullet’s ability to overcome air resistance. Higher BC values indicate better aerodynamic efficiency.
* **Muzzle Velocity:** The speed of the bullet as it exits the firearm’s barrel.
* **Muzzle Energy:** The kinetic energy of the bullet as it exits the barrel, calculated from its mass and velocity.
* **Trajectory:** The path of the bullet in flight, influenced by gravity and air resistance.
* **Drop:** The vertical distance the bullet falls over a given distance.
* **Wind Drift:** The horizontal displacement of the bullet due to wind.

The Subsonic Advantage

The primary advantage of subsonic ammunition is noise reduction, particularly when used with a suppressor. However, subsonic rounds also present unique ballistic challenges. Because they travel at lower velocities, they typically have less energy and a more curved trajectory than supersonic rounds. The Hornady Sub-X 190 S is engineered to mitigate these challenges through its design and construction.

Importance of Ballistic Coefficient (BC) in Subsonic Rounds

While often overlooked with subsonic rounds, the Ballistic Coefficient (BC) remains vitally important. A higher BC means the bullet will retain its velocity better over distance, resulting in a flatter trajectory and improved accuracy, even at subsonic speeds. Hornady likely optimized the Sub-X 190 S for the best possible BC within the constraints of subsonic performance and bullet weight.
