Quick Answer
To sight in a rifle with new bullets, shoot a group of 5-10 shots at a 100-yard target using a consistent ammunition brand and type, then adjust the scope as needed to achieve a tight group. This process should be repeated with multiple bullet types to ensure the rifle's accuracy. Always record the results for future reference.
Choosing the Right Bullet Type
When selecting a bullet type for your rifle, consider the specific hunting application. For controlled expansion bullets, which are designed to expand upon impact, it’s essential to choose a bullet that matches your rifle’s caliber and intended use. For example, if you’re hunting large game, a 7mm Remington Magnum with a 180-grain controlled expansion bullet would be a suitable choice.
Setting Up the Shooting Range
To accurately sight in your rifle, set up a 100-yard target and ensure a stable shooting position. Use a bipod or shooting sticks to minimize movement and a consistent shooting rest. For most rifles, a 1-inch aiming point at 100 yards translates to approximately 3.6 inches at 200 yards, so it’s crucial to choose a bullet that maintains this trajectory. Shoot a group of 5-10 shots with the new bullet to establish a baseline for accuracy.
Sight-In and Adjustment Techniques
When adjusting the scope for accuracy, aim for a 1-inch group at 100 yards. To make adjustments, use a consistent, incremental method, such as adjusting the scope in 0.25 MOA increments. If the group is high, adjust the scope down; if it’s low, adjust the scope up. Record the results and repeat the process with multiple bullet types to ensure the rifle’s accuracy. It’s also essential to consider atmospheric conditions, such as temperature and humidity, which can affect bullet trajectory.
