Can you achieve sub-MOA accuracy with .264 Winchester Magnum?

Load Development

Achieving sub-MOA accuracy with the .264 Winchester Magnum requires precise load development. The optimal powder charge for a .264 WM can vary greatly depending on the specific cartridge case, bullet weight, and desired velocity. For example, a 130-grain bullet loaded to 55 grains of H1000 powder can produce velocities over 3,000 feet-per-second while maintaining sub-MOA accuracy. In contrast, a 140-grain bullet loaded to 52 grains of Varget powder may require slight adjustments to achieve optimal accuracy.

Rifle and Barrel Requirements

A high-quality rifle and barrel are essential for achieving sub-MOA accuracy with the .264 WM. A heavy, fluted barrel with a 1:8 or 1:9 twist rate can help stabilize the bullet and reduce barrel harmonics. In addition, a rifle with a consistent, free-floated barrel and a sturdy stock can help minimize the effects of shot-to-shot variation.

Practical Application

In practical application, achieving sub-MOA accuracy with the .264 WM often requires a combination of load development, rifle selection, and shooting technique. With a well-developed load and a high-quality rifle, it’s possible to consistently place shots within 1 MOA at 100 yards, making the .264 WM a suitable choice for long-range hunting and target shooting. This level of accuracy can be achieved through careful attention to detail and a willingness to experiment with different loads and techniques.
