Redding .339" Heat-Treated Steel Neck Sizing Bushing

Elevate your reloading game with the Redding .339" Heat-Treated Steel Neck Sizing Bushing. Crafted with precision and durability in mind, this reloading accessory simplifies the process of achieving precise neck sizing for your cartridges.

Key Features:

• Heat Treated Steel: The bushing is constructed from heat-treated steel for superior strength and longevity. With a surface hardness of Rc 60-62, it reduces sizing effort while maintaining durability.
• Wide Size Range: Available in sizes from .185" to .368" in .001" increments, ensuring that you can find the perfect fit for your specific cartridge neck.

Choosing the Right Bushing Size:

Selecting the correct bushing size is crucial for achieving optimal results in your reloading process. Here are two reliable methods to determine the right size:

1. Measure Loaded Cartridges: Measure the neck diameter of several loaded or dummy cartridges using an accurate micrometer. Subtract 0.001" from the measurement of the cartridge with the smallest average diameter. This accounts for a slight amount of spring back and ensures a proper press fit for your bullet.
2. Calculate Neck Diameter: Measure the neck wall thickness of your cartridge cases with a ball-type or tubing micrometer. Double this measurement and add the bullet diameter to calculate the neck diameter of a loaded cartridge. Subtract 0.001" from this figure to determine the appropriate bushing size.

It's important to note that these methods assume that your cases have fairly uniform neck wall thickness. If variations exceed 0.002", you may need to choose a bushing slightly smaller than your calculations indicate. In such cases, a size button in the die can help determine the final inside neck diameter accurately.
