Quick Answer
Beyond 200 yards, bullet drop significantly affects accuracy, requiring precise adjustments in elevation to compensate for the trajectory of various calibers and weights.
Understanding Bullet Drop
Bullet drop is a critical consideration for long-range shooting, particularly when hunting with a rifle. For every 100 yards, a bullet drops approximately 3 inches at 1,000 yards, assuming a 40-degree angle of fire. This means that at 300 yards, a bullet will have dropped around 9 inches. Understanding this concept is essential for zeroing your rifle and compensating for the ballistics of your chosen caliber.
Compensating for Bullet Drop
To compensate for bullet drop, you must adjust the point of aim to intersect with the target at the optimal range. This is achieved by adjusting the elevation on your scope or rifle. A general rule of thumb is to adjust the elevation by 1 MOA (minute of angle) for every 100 yards. For example, if you’re shooting at 300 yards and your bullet drops 9 inches, you would need to adjust the elevation by 3 MOA. This may vary depending on your specific rifle and ammunition.
Zeroing Your Rifle
Zeroing your rifle involves adjusting the point of aim to intersect with the point of impact at a specific range, typically 100 yards. This ensures that your rifle is accurately sighted in and ready for longer-range shots. To zero your rifle, start by setting the elevation to the minimum value. Then, fire a shot at 100 yards and observe the impact. Adjust the elevation as necessary until the impact matches the point of aim. This process should be repeated at various ranges to ensure the rifle remains accurately sighted in for different distances.
