Ballistic Performance: .30-06 vs. 7.62
When comparing the ballistic performance of the .30-06 vs 7.62, several factors come into play, including bullet weight, muzzle velocity, and ballistic coefficient. Generally, the .30-06, with its longer case, has the potential to achieve slightly higher velocities, especially with heavier bullets. However, modern .308 loads have narrowed the gap considerably.
Velocity and Energy: The .30-06 typically boasts a slight edge in muzzle velocity, particularly when using heavier bullets (180 grains or more). This translates to a slightly flatter trajectory and more energy on target at longer ranges. However, high-performance .308 loads can closely match the .30-06’s performance with lighter bullets.
Trajectory: Due to the higher velocity of the .30-06, it generally exhibits a flatter trajectory, meaning less bullet drop at longer distances. This can be an advantage for hunters shooting at extended ranges.
Recoil: The 7.62x51mm NATO generally produces less recoil than the .30-06 Springfield. This is due to the .308’s smaller case capacity and typically lighter bullet weights. The reduced recoil can make the .308 more comfortable to shoot, especially for extended periods, and can improve accuracy, especially for follow-up shots.
Bullet Weight and Selection: One of the .30-06’s strengths is its versatility in terms of bullet weight. It can effectively shoot bullets ranging from 110 grains to 220 grains, offering a wide range of options for different applications. The .308 Winchester typically performs best with bullets in the 150-180 grain range, although lighter and heavier options are available.
