Are there specific loading techniques for Nosler Partition bullets?

Seating Depth and Powder Charge

When loading Nosler Partition bullets, it’s essential to maintain the correct seating depth. The recommended seating depth varies by caliber, but in general, you should seat the bullet to an OAL (overall length) of 0.020"-0.030" less than the maximum allowed by the rifle’s chamber. For example, in a .308 Winchester, you would seat the bullet to 2.810"-2.820" OAL. Additionally, the recommended powder charge for Nosler Partition bullets is around 45-50 grains of IMR 4064 in a .308 Winchester, but this can vary depending on the specific rifle and loading conditions.

Loading and Performance Considerations

When loading Nosler Partition bullets, it’s essential to consider the bullet’s construction and performance characteristics. The Partition bullet features a copper jacket with a lead core and a distinctive partition between the lead and copper. This design allows the bullet to expand more uniformly upon impact, reducing the risk of core separation and improving accuracy. When loading these bullets, it’s essential to use a consistent powder charge and seating depth to ensure consistent performance. Additionally, the use of a bullet seater plug can help maintain the correct seating depth and prevent over-seating, which can lead to inconsistent accuracy and reduced performance.
