Quick Answer
Sighting in a new bolt-action rifle involves ensuring proper zero at 100 yards, then adjusting for longer ranges. This process typically involves firing groups of shots at a target, analyzing the results, and making adjustments to the scope or rifle as needed. Use a chronograph or high-accuracy target to aid in this process.
Setting Up the Rifle
When sighting in a new bolt-action rifle, the first step is to ensure the rifle is properly aligned and the scope is securely fastened. Use a bubble level on the rifle or scope to confirm the rifle is level, and perform a scope alignment check to ensure the reticle is properly aligned with the rifle’s bore. Next, set up your target at 100 yards and ensure a consistent shooting position.
The Sighting-in Process
Begin by firing a group of shots at the target, using the same ammunition and shooting position each time. Use a chronograph to measure the velocity of each shot, which will help you identify any variations in the rifle’s performance. Start by adjusting the scope’s elevation knob, making small adjustments (0.25-0.5 MOA) and firing a group of shots after each adjustment. Once you’ve achieved a consistent group size, move on to adjusting the windage knob.
Tips and Tricks
To improve your sighting-in process, use a high-accuracy target with small aiming points, such as a 10-ring target or a ballistic target with small aiming circles. Additionally, use a consistent shooting position and ammunition, and make small adjustments to the scope after each shot. Consider using a rifle with a built-in elevation adjustment, such as a rifle with a Picatinny rail and a scope with a built-in elevation adjustment. This will allow you to make precise adjustments to the scope without having to re-zero the rifle.
