Essential Reloading Components and Tools

The foundation of safe and accurate reloading lies in understanding the components involved and using the correct tools. Let’s break down the essentials.

Selecting the Right Brass

The brass case is the backbone of your .308 Winchester ammunition. Selecting quality brass is crucial for consistent performance and longevity. Brass should be of consistent quality and weight. Brands like Nosler themselves, along with Federal, Winchester, and Lapua, are excellent choices. Proper case preparation is essential. This includes:

Cleaning: Removing any dirt, debris, or carbon buildup from inside and outside the case.

Inspection: Examining the case for cracks, splits, or other signs of damage. Discard any damaged cases.

Full-Length Sizing or Neck Sizing: Sizing the case back to the original factory dimensions. Full-length sizing is typically used for hunting rifles or for rifles where the same case will be used by different shooters. Neck sizing is often used for rifles where the same cases are used, shot and reloaded over and over by the same shooter.

Trimming: Cutting the case to the correct length to ensure consistent headspace and prevent pressure issues.

Deburring and Chamfering: Removing any sharp edges from the case mouth to ease bullet seating.

Primer Pocket Cleaning: Ensuring the primer pocket is clean for proper primer seating.

Picking the Right Primers

Primers initiate the combustion process. They come in different types and sizes. For the .308 Winchester, large rifle primers are generally recommended. Consider these factors:

Standard vs. Magnum Primers: Choose the appropriate primer type for the powder being used. Some slow-burning powders may benefit from magnum primers, but this should always be confirmed using load data.

Brand Selection: Consistency in primer ignition is important, so choose a reputable brand like Federal, CCI, or Winchester.

Exploring the World of Powders

Powder selection is a critical factor in achieving optimal performance. Various powders are compatible with the .308 Winchester, each with its own burn rate characteristics and ideal bullet weight range. Some popular options include:

IMR 4064: A classic choice known for its accuracy and versatility, especially with lighter bullets.

Varget: Popular for its temperature stability and accuracy potential across a range of bullet weights.

Reloder 15: Offers excellent velocity potential and accuracy, often preferred with heavier bullets.

H4895: Another temperature-stable option, often favored for its ability to achieve excellent velocity, especially with lighter bullets.

Hodgdon CFE 223: Produces excellent accuracy and velocity, especially with medium to heavier bullets, and offers copper fouling elimination.

When working with any powder, always adhere to these safety protocols:

Start Low, Go Slow: Always begin with the starting load listed in the Nosler load data and gradually increase the powder charge, monitoring for pressure signs.

Never Exceed Maximum Loads: Never exceed the maximum powder charge listed in the load data.

Proper Powder Handling: Store powder in a cool, dry place, away from heat, sparks, and open flames.
