Redding .306" Heat-Treated Steel Neck Sizing Bushing - 73306

Elevate your reloading precision with the Redding .306" Heat-Treated Steel Neck Sizing Bushing. Crafted with precision and durability in mind, this bushing is designed to enhance your reloading experience.

Key Features:

• Heat-Treated Steel: Constructed from heat-treated steel, this neck sizing bushing offers exceptional strength and longevity.
• Hand-Polished Sizing Diameters: The sizing diameters are meticulously hand-polished to ensure a smooth and consistent surface hardness of Rc 60-62. This reduces the effort required for sizing cartridges.
• Wide Range of Sizes: Available in sizes ranging from .185" to .368" in precise .001" increments, allowing you to find the perfect fit for your reloading needs.
• Accurate Sizing: Determine the ideal bushing diameter with ease. Measure the neck diameter of loaded or dummy cartridges using an accurate micrometer and subtract 0.001" from the smallest average measurement to create a proper press fit for your bullet.
• Alternative Sizing Methods: If you prefer alternative sizing methods, you can measure the neck wall thickness of cartridge cases with a ball-type or tubing micrometer, double the measurement, and add the bullet diameter to calculate the neck diameter of a loaded cartridge. Subtract 0.001" from this figure to find your desired bushing size.
• For New Cases: If you're working with new cases, determine neck wall thickness as described above or seat boat-tail bullets in a few cases and measure their neck diameter. New cases often have a small enough neck diameter to hold a bullet without sizing.
• Using a Caliper: As a last resort, you can measure the neck wall thickness of cases with a caliper. Keep in mind that calipers may have reduced measuring accuracy, so multiple measurements may be needed to select the correct bushing size.
• Uniform Neck Wall Thickness: To achieve optimal results, it's important that the cases being sized have a fairly uniform neck wall thickness or have been neck turned. If the neck wall thickness varies more than 0.002", consider using a bushing slightly smaller than your calculations indicate and use a size button in the die to determine the final inside neck diameter.

Invest in the Redding .306" Heat-Treated Steel Neck Sizing Bushing - 73306 for precise and efficient cartridge sizing. Whether you're a seasoned reloader or just starting, this high-quality bushing is a valuable addition to your reloading toolkit.
