Can You Use a Rangefinder for Shooting Running Deer?

Choosing the Right Rangefinder

When selecting a rangefinder for hunting running deer, consider one with a high accuracy rating, typically above 90%, and a scan mode that can quickly lock onto multiple targets. For example, Leupold’s RX-1200i has a 99% accuracy rating and a scan mode that can lock onto targets in 0.3 seconds. Additionally, opt for a rangefinder with a long battery life and rugged construction to withstand harsh hunting environments.

Techniques for Accurate Rangefinder Use

To use a rangefinder effectively for running deer shots, practice scanning and locking onto targets quickly. Keep the rangefinder steady, using both hands if necessary, and try to get a clear line of sight to the deer. When the deer is running, aim for the spot where it will be when the bullet reaches it, rather than the deer’s current position. For example, if the deer is running at 20 mph and you’re using a 300-grain bullet with a 1,000 fps muzzle velocity, the bullet will travel approximately 1.4 seconds to reach the deer. During this time, the deer will travel around 28 yards, so aim for 28 yards ahead of the deer’s current position.

Tips for Accounting for Deer Movement

When accounting for the deer’s movement, consider the time it takes for the bullet to reach the deer and the distance it will travel during that time. Use a ballistic calculator or consult a ballistics chart to determine the exact holdover or windage needed for your specific rifle and bullet combination. For example, if the deer is running at a 45-degree angle to the shooter, you’ll need to account for the wind deflection and the bullet’s drop over the distance.
