5. Understanding Bullet Weight and Its Impact on Speed
The weight of a sniper bullet is a critical factor that affects its velocity and overall performance.
Relationship Between Bullet Weight and Velocity
Generally, lighter bullets travel faster than heavier bullets, given the same amount of propellant and other conditions. This is due to the basic principle of physics: it takes less energy to accelerate a lighter object to a certain speed than a heavier one. According to ballistic studies at the University of Utah, decreasing bullet weight by 10% can increase muzzle velocity by approximately 3-5%.
Optimal Bullet Weight for Different Sniper Applications
The optimal bullet weight depends on the specific application, such as long-range accuracy, penetration, or energy transfer.
