The .30-06, with its slightly larger case capacity, can sometimes achieve marginally higher velocities, especially with heavier bullets (180 grains or more). However, modern 7.62x51mm NATO loads have closed this gap considerably.

Trajectory: Due to their similar velocities, the .30-06 and 7.62x51mm NATO exhibit fairly similar trajectories out to moderate ranges (e.g., 300-400 yards). Beyond that, the higher ballistic coefficient of certain .30-06 bullets can provide a slight advantage in terms of flatter trajectory and reduced wind drift.

Energy: Again, with similar bullet weights and velocities, the .30-06 and 7.62x51mm NATO deliver comparable energy on target. Both cartridges pack a significant punch, making them suitable for a wide range of game animals and target shooting applications. The .30-06, with its potential for heavier bullets, can sometimes offer a slight edge in terms of retained energy at longer ranges.

It’s important to note that ballistic performance can vary significantly depending on the specific load, bullet type, and barrel length. Always consult ballistic charts and conduct thorough testing with your chosen rifle and ammunition to determine the optimal setup for your needs.
