Quick Answer
To zero a .264 Winchester Magnum scope at long range, start with a 100-yard zero and adjust the elevation for a 400-yard zero, then fine-tune the windage for a 600-yard zero. Use a chronograph to record bullet velocity for accurate adjustments. Use a ballistic calculator or shooting software for precise calculations.
Long-Range Zeroing Techniques
When zeroing a .264 Winchester Magnum scope for long-range shooting, the primary goal is to achieve a 400-yard zero, as this allows for a relatively flat trajectory out to 600 yards. Start by setting your scope to a 100-yard zero and record the point of impact. This will serve as your baseline for further adjustments.
Bullet Drop and Windage Adjustments
Using a chronograph, record the bullet velocity for your specific load. For a .264 Winchester Magnum, a typical velocity range is 2,900-3,000 fps. Plug this value into a ballistic calculator or shooting software, along with your scope’s MOA settings and the rifle’s ballistic coefficient. This will provide you with the necessary elevation adjustments to reach a 400-yard zero. For example, a 3,000 fps bullet will drop approximately 22.4 inches at 400 yards, and 44.5 inches at 600 yards.
Fine-Tuning for Wind and Elevation
Once you have established a 400-yard zero, fine-tune the windage for a 600-yard zero. This involves adjusting the windage knob to compensate for the bullet’s drift due to crosswinds. Use the ballistic calculator to determine the exact windage adjustment required. Additionally, double-check your elevation settings to ensure they remain accurate for the longer range.
