Effects of altitude on bullet velocity when hunting prairie dogs?

Effects of Altitude on Bullet Velocity

When hunting prairie dogs at high altitudes, it’s essential to understand how altitude affects bullet velocity. For every 1,000 feet of elevation gain, the air pressure decreases by approximately 1 psi, resulting in a 1-2% decrease in bullet velocity. For example, a 6,000-foot elevation can result in a 12-24% decrease in bullet velocity compared to sea level.

Choosing the Right Ammunition

To account for the effects of altitude on bullet velocity, hunters should choose ammunition that is specifically designed for high-altitude shooting. These bullets are typically heavier and have a longer ogive, which helps to maintain their velocity at higher elevations. For prairie dog hunting, a 55-60 grain bullet with a muzzle velocity of 2,800-3,000 feet per second is a good starting point.

Techniques for Accurate Shooting at High Altitude

To ensure accurate shooting at high altitude, hunters should use a rifle scope with a high-powered magnification (10x or higher) and a reticle that provides accurate bullet drop compensation. They should also use a ballistic calculator to determine the correct holdover for their specific rifle and ammunition. Additionally, taking regular breaks to acclimate to the high altitude and using a spotting scope to estimate the distance to the target can help hunters make more accurate shots.
