Quick Answer
Elevation affects bullet trajectory by altering the air density and temperature, which in turn affect the bullet's velocity and air resistance, resulting in a greater drop at higher elevations.
Effects of Elevation on Bullet Trajectory
When shooting at high elevations, it’s essential to understand how the atmosphere changes. At higher elevations, the air is thinner and temperatures are colder. This reduction in air density and temperature increases the bullet’s velocity, but also increases air resistance, resulting in a greater drop from the intended point of impact. For example, at 7,000 feet, a 100-yard shot will drop approximately 2-3 inches due to the thinner air, whereas at sea level, the same shot will drop around 1-2 inches.
Compensating for Elevation in Prairie Dog Shooting
To accurately compensate for elevation in prairie dog shooting, use a ballistic calculator or consult a ballistic chart specific to your rifle and ammunition. For instance, if you’re shooting a .22-250 Remington at 7,000 feet, you may need to add 2-3 inches to your point of aim for a 100-yard shot. It’s also crucial to take into account any changes in wind speed and direction at high elevations, as the thinner air can make wind drift more pronounced. Consider using a spotter to help track the bullet’s trajectory and make necessary adjustments.
Additional Considerations for High-Elevation Shooting
In addition to the effects of elevation on bullet trajectory, high-altitude shooting also requires consideration of the reduced oxygen levels and increased UV radiation. Make sure to acclimate yourself to the higher elevation by drinking plenty of water and taking regular breaks to avoid altitude sickness. Also, consider using a rifle with a heavy barrel to reduce the effects of the increased wind and temperature fluctuations at high elevations.
