Understanding Cartridge Ballistics: A Foundation

Before we delve into the specifics of the .308 and 7mm Rem Mag, it’s crucial to understand the fundamentals of cartridge ballistics. Ballistics encompasses the study of projectile motion, covering everything from the moment the cartridge is fired to when the bullet impacts the target. Several key factors influence a cartridge’s ballistic performance:

* **Velocity:** The speed at which the bullet travels, typically measured in feet per second (fps). Higher velocity generally translates to flatter trajectories and greater energy.
* **Trajectory:** The path the bullet takes in flight. A flatter trajectory reduces the need for holdover adjustments at longer distances.
* **Energy:** The kinetic energy the bullet possesses, measured in foot-pounds (ft-lbs). Higher energy is essential for effective terminal performance, especially on larger game.
* **Ballistic Coefficient (BC):** A measure of a bullet’s ability to overcome air resistance. Higher BC bullets retain velocity and energy better over longer distances.
* **Recoil:** The force felt by the shooter when the rifle is fired. Higher recoil can affect accuracy and shooting comfort.

Understanding these basic principles will provide a solid foundation for comparing the .308 and 7mm Rem Mag.

The .308 Winchester: A Versatile Workhorse

The .308 Winchester, also known as 7.62x51mm NATO, is a centerfire rifle cartridge that has enjoyed widespread popularity since its introduction in the 1950s. Developed as a civilian version of the 7.62x51mm NATO military cartridge, the .308 quickly gained acceptance among hunters, target shooters, and law enforcement agencies. Its versatility stems from its ability to deliver excellent accuracy and effective terminal performance in a relatively compact and manageable package. The .308 is suitable for a wide range of game, from deer and antelope to elk and even black bear at reasonable distances.
