Ballistic Coefficient and Trajectory
The ballistic coefficient (BC) of a bullet is a measure of its ability to overcome air resistance during flight. Hornady Precision Hunter bullets typically have high BCs, which translates to flatter trajectories and less wind drift. Knowing the BC of your bullet allows you to accurately predict its trajectory using ballistic calculators or apps. Trajectory refers to the path of the bullet from the muzzle to the target. A 100 yard zero means that the bullet’s path crosses the line of sight at 100 yards. Beyond this distance, the bullet will drop below the line of sight due to gravity. Ballistic charts can help you understand the bullet drop at different ranges.
Why a 100 Yard Zero?
A 100 yard zero is a common starting point for many shooters for several reasons. It provides a relatively flat trajectory within typical hunting distances, simplifying holdover adjustments for shots at shorter ranges.

The Zeroing Process: Step-by-Step Guide
Zeroing your .300 Win Mag with Hornady Precision Hunter ammunition requires a systematic approach. Follow these steps to achieve a precise 100 yard zero:
Step 1: Bore-Sighting
Before heading to the range, bore-sight your rifle to get the scope roughly aligned with the barrel. This will save time and ammunition during the zeroing process. A bore-sighting tool can be used, or you can remove the bolt and visually align the scope with the target. Adjust the scope until the reticle is centered on the target when looking through the bore.
Step 2: Initial Shots at 25 Yards
Begin by shooting at a target placed at 25 yards. This will help you get your shots on paper and make initial adjustments to the scope. Fire a group of three shots and observe the impact point. Adjust the scope’s windage and elevation turrets to move the group closer to the center of the target. Remember to consult your scope’s instructions for the adjustment value per click (e.g., 1/4 MOA or 1/2 MOA).
Step 3: Moving to 100 Yards
Once you have a consistent group at 25 yards, move the target to 100 yards. Fire another group of three shots and carefully analyze the impact point. Use a spotting scope or binoculars to get a clear view of the target. Measure the distance between the center of the group and the center of the target. This measurement will determine the amount of adjustment needed on your scope.
Step 4: Adjusting the Scope
Adjust the scope’s windage and elevation turrets based on the measured distance and your scope’s adjustment value per click. For example, if your group is 2 inches low and 1 inch to the right, and your scope adjusts in 1/4 MOA increments, you would need to adjust the elevation up by 8 clicks (2 inches / 0.25 MOA per click) and the windage left by 4 clicks (1 inch / 0.25 MOA per click). Fire another group of three shots to confirm your adjustments.
Step 5: Fine-Tuning and Confirmation
Repeat the adjustment process until your shots are consistently hitting the center of the target at 100 yards. Aim for a group size of 1 inch or less. Once you are satisfied with your zero, fire a final group of five shots to confirm the accuracy and consistency of your rifle and ammunition. Record your zero settings (windage and elevation) for future reference. Understanding the .300 Win Mag’s performance with Hornady Precision Hunter is key to consistent accuracy.
Factors Influencing Your .300 Win Mag Zero
Several factors can affect your .300 Win Mag zero and overall accuracy. Being aware of these factors and taking steps to mitigate their impact can significantly improve your shooting performance.
