Core Concepts & Advanced Principles

The core of AK-47 bullet specifications lies in understanding the relationships between bullet weight, velocity, and ballistic coefficient. Bullet weight, typically around 123 grains (8 grams), affects the bullet’s momentum and terminal energy. Velocity, generally around 2,330 feet per second (710 meters per second), determines the bullet’s flight time and trajectory. The ballistic coefficient (BC) measures the bullet’s ability to overcome air resistance; a higher BC results in a flatter trajectory and greater retained velocity at longer ranges. Advanced principles involve understanding how these factors interact to influence the bullet’s performance under various conditions. For example, a heavier bullet might offer greater penetration, while a lighter bullet might provide a flatter trajectory at shorter distances. The spin rate imparted by the rifle’s rifling also plays a crucial role in stabilizing the bullet in flight.
