Do Different Ammunitions Affect Performance on Angled Shots?

Trajectory and Ammunition

When taking angled shots, the bullet’s trajectory plays a crucial role. Different ammunition types have varying ballistic coefficients, which affect their flight paths. For example, a 150-grain 30-06 Springfield cartridge with a ballistic coefficient of 0.475 will drop approximately 24.5 inches at 500 yards, while a 175-grain 30-06 Springfield cartridge with a ballistic coefficient of 0.505 will drop around 22.5 inches at the same distance. This means that the heavier, more aerodynamic bullet will maintain its trajectory better.

Angle and Elevation Adjustment

In uphill shots, the bullet will drop more due to gravity, while in downhill shots, it will drop less due to the increased distance. To compensate, shooters can adjust their aim point. For every 1,000 feet of elevation gain, aim 3-4 inches high, and for every 1,000 feet of elevation loss, aim 2-3 inches low. For example, at 500 yards uphill on a 1,000-foot elevation gain, aim 12-16 inches high.

Real-World Application

To put this into practice, consider the following scenario: a shooter is taking a 300-yard uphill shot on a 500-foot elevation gain. Using a 150-grain 30-06 Springfield cartridge with a ballistic coefficient of 0.475, they should aim 9-12 inches high to compensate for the drop. In a real-world situation, this means aiming for the spot where the deer’s vitals would be at the base of the hill, not at the top where the deer is visible.
