Quick Answer
For Nosler Partition bullets, a general starting point is a powder charge of 50-55 grains for a .270 Winchester, 55-60 grains for a .30-06 Springfield, and 65-70 grains for a .300 Winchester Magnum, depending on the specific rifle, barrel length, and desired performance.
Choosing the Right Powder Charge
When selecting a powder charge for Nosler Partition bullets, it’s essential to consider the rifle’s bore diameter, barrel length, and the desired performance level. A general starting point is a powder charge that’s between the minimum and maximum loads listed in the reloading manual. For example, in the .270 Winchester, a starting point of 50-55 grains of powder is a good starting point. This allows for a safe and accurate load while also producing decent velocity and expansion.
Understanding Bullet Performance
Nosler Partition bullets are designed to provide deep penetration and consistent expansion. To achieve this, it’s crucial to select a powder charge that produces a velocity range of 2,800-3,000 feet per second (fps) for the .270 Winchester, 2,900-3,100 fps for the .30-06 Springfield, and 3,000-3,200 fps for the .300 Winchester Magnum. This velocity range ensures that the bullet expands consistently and penetrates deep into the target.
Reloading and Safety Considerations
When reloading with Nosler Partition bullets, it’s essential to follow proper safety protocols and reloading procedures. This includes using the correct powder charge, seating the bullet to the correct depth, and ensuring that the rifle is properly maintained and cleaned. Additionally, it’s crucial to start with a lower powder charge and gradually increase it to the desired level to avoid overloading the rifle and compromising safety.
