.223 vs .308 for deer hunting — which is better?

Ballistic Performance

When it comes to deer hunting, the .308 Winchester cartridge is generally preferred over the .223 Remington. This is due to its higher kinetic energy, which is essential for taking down larger game. The .308 delivers approximately 1900 ft-lbs of energy at 500 yards, while the .223 delivers around 500 ft-lbs at the same range. This significant difference in energy transfer makes the .308 better suited for deer hunting.

Rifle Accuracy and Field Tuning

When choosing a rifle for deer hunting, accuracy is crucial. To achieve optimal accuracy, it’s essential to field tune your rifle. This involves adjusting the scope’s zero, ensuring the rifle is properly sighted-in, and making any necessary adjustments to the trigger pull. A good rule of thumb is to zero your scope at 100 yards, then adjust the zero marks to compensate for bullet drop at longer ranges. For example, if you’re hunting at 200 yards, aim 4 inches high to account for the bullet’s trajectory.

Practical Application

In real-world hunting situations, the .308’s flatter trajectory and higher kinetic energy make it more effective at longer ranges. When hunting at distances over 200 yards, a .308 is generally preferred. However, it’s essential to remember that accuracy and shot placement are more critical than cartridge choice. Regardless of the caliber, a well-placed shot at close range is often more effective than a shot at longer range, even with a more powerful cartridge.
