Introduction:
The .308 Winchester remains a hugely popular cartridge, beloved for its versatility, accuracy, and availability. Whether you're hunting deer, competing in long-range shooting, or simply enjoying recreational target practice, finding the right ammunition is crucial. For many reloaders, Nosler components offer a path to exceptional accuracy and performance. This in-depth guide explores Nosler .308 load data, providing information to help you safely and effectively create your own high-quality ammunition. We'll cover various bullet weights, powder choices, and primers, emphasizing safety and precision.
Understanding Nosler Components
Nosler is renowned for its high-quality bullets, offering a wide range of designs optimized for various applications. For .308 Winchester reloading, you'll find options like:
- Nosler Ballistic Tip (BT): Known for its excellent accuracy and expansion, the BT is a popular choice for hunting. The polymer tip enhances ballistic coefficient and provides reliable expansion on game.
- Nosler AccuBond (AB): A bonded core design that delivers exceptional accuracy and consistent weight retention, making it ideal for hunting larger game. The bonded construction ensures the core and jacket remain together upon impact.
- Nosler Partition: This classic design features a lead core separated by a partition. This creates superior weight retention and penetration, ideal for tough game.
Choosing the right bullet will significantly influence your load data. Always refer to the specific bullet's manufacturer's data sheet for recommended starting loads.
Selecting the Right Powder
Powder selection is critical for safe and effective reloading. Popular choices for .308 Winchester loads using Nosler bullets include:
- IMR 4064: A versatile, medium-burning powder often used for various .308 loads, offering good accuracy and moderate recoil.
- IMR 4895: Another popular choice known for its reliability and accuracy across a range of bullet weights.
- RL-15: A slightly faster powder offering good accuracy and less recoil compared to IMR 4064 and IMR 4895. It's well-suited for lighter bullets.
- Varget: A highly accurate and versatile powder known for its consistent performance across different conditions. Very popular for match-grade ammunition.
Important Note: Powder choice significantly impacts pressure. Never exceed the maximum recommended load data provided by the powder manufacturer and Nosler's recommendations.
Primer Selection
While the primer type plays a less significant role than powder and bullet selection, it still impacts consistency and ignition. For .308 Winchester reloading, standard large rifle primers are suitable. Avoid using magnum primers unless specifically called for in your chosen load data.
