Do .308 Winchester handloads offer significant accuracy improvements?

Load Development Key to Accuracy

Accurate load development is crucial for achieving optimal performance from .308 Winchester handloads. Start by selecting a high-quality brass case and primer, as these components can significantly impact overall accuracy. For example, Federal Gold Medal Match cases have a reputation for consistency and are a good choice for handloaders. Next, choose a suitable powder that complements the bullet and case combination. In .308 Winchester, powders like H1000, RL22, and Varget are popular choices for achieving high accuracy. When developing a load, experiment with different powder charges and seat depths to find the optimal combination for your specific rifle and shooting conditions.

Bullet Selection and Seating

The bullet selection process is critical in achieving accuracy with .308 Winchester handloads. Choose a bullet design that is suitable for deer hunting, such as the Sierra MatchKing 168gr or the Hornady A-MAX 155gr. Bullet seating depth is also crucial, as improper seating can lead to inconsistent accuracy. A general rule of thumb is to seat the bullet at or slightly into the rifling, depending on the specific rifle and bullet combination. For example, in a Remington 700, a bullet seating depth of 0.005-0.010" into the rifling may be optimal.

Rifle Setup and Maintenance

A well-maintained rifle is essential for achieving accuracy with .308 Winchester handloads. Regularly clean and inspect the rifle’s barrel, ensuring that no debris or fouling is present. Additionally, check the rifle’s action and trigger for proper function and adjust as necessary. Properly bedding the action and stock can also improve accuracy, as a well-bedded rifle will be less prone to movement and vibration. In a typical .308 Winchester rifle, accuracy improvements of 1-2 MOA can be achieved through proper rifle setup and maintenance.
