Quick Answer
To zero a long-range hunting scope, it's essential to start at 100 yards and use a high-powered scope with adjustments that allow for precise clicks, then gradually increase the distance in increments of 25 or 50 yards until the bullet hits its mark. This process is best done in a controlled environment with a reliable target and a spotting scope to track the bullet's trajectory. Properly zeroing a long-range scope requires patience and attention to detail.
Zeroing at 100 Yards
When zeroing a long-range scope, start at 100 yards to establish a baseline for your adjustments. This distance allows you to make precise adjustments while minimizing the impact of external factors like wind and bullet drop. Use a high-powered scope with adjustments that allow for at least 1 MOA per click to ensure you can make fine adjustments.
Increasing Distance in Increments
Once you’ve established a baseline at 100 yards, gradually increase the distance in increments of 25 or 50 yards. This will allow you to track the bullet’s trajectory and make adjustments as needed. For example, if you’re using a 6.5mm Creedmoor rifle, you’ll need to account for approximately 17 inches of bullet drop at 400 yards. By increasing the distance in 25-yard increments, you can make adjustments to your scope and track the bullet’s trajectory with greater accuracy.
Tracking Bullet Trajectory
To accurately track the bullet’s trajectory, use a spotting scope to observe the impact point. Take note of the distance and the direction of the bullet’s drop, then make adjustments to your scope accordingly. Keep in mind that bullet drop increases exponentially with distance, so small adjustments can have a significant impact on the bullet’s trajectory. By carefully tracking the bullet’s trajectory and making precise adjustments, you can zero your long-range scope with confidence.
