Understanding the Chart’s Metrics
The chart makes use of a number of metrics to supply a complete view of every cartridge’s ballistics:
- Bullet Weight: Measured in grains (gr), indicating the load of the projectile.
- Ballistic Coefficient: This numerical worth represents a bullet’s potential to beat air resistance. The next ballistic coefficient means the bullet retains velocity and power higher over distance.
- Muzzle Velocity: The velocity of the bullet because it leaves the muzzle of the rifle, measured in ft per second (fps).
- Vary Increments: Distances at which the bullet’s efficiency is measured, sometimes in yards.
- Drop: The vertical distance the bullet falls on account of gravity, measured in inches.
- Velocity at Vary: The bullet’s velocity at a particular distance, measured in fps.
- Vitality at Vary: The kinetic power of the bullet at a particular distance, measured in foot-pounds (ft-lbs). This means the bullet’s potential for impression and tissue injury.
- Wind Drift: The horizontal distance the bullet is deflected by a crosswind, measured in inches, given a relentless wind velocity.
Dissecting the Information: Analyzing Efficiency
