Redding .307" Heat-Treated Steel Neck Sizing Bushing for Precision Reloading

Redding .307" Heat-Treated Steel Neck Sizing Bushing - 73307

Introducing the Redding .307" Heat-Treated Steel Neck Sizing Bushing, a crucial tool for precision reloading. Made from heat-treated steel with a surface hardness of Rc 60-62, this bushing ensures a smooth and efficient sizing process. It's designed to reduce the effort required in neck sizing, providing a seamless experience for reloaders.

Range of Sizes and Polished Diameter

The bushings are available in sizes ranging from .185_ to .368_ in .001_ increments, each hand-polished to ensure optimal performance. This range accommodates a wide variety of cartridges, making it a versatile choice for different reloading needs.

Optimal Sizing Methodology

To determine the proper diameter bushing, measure the neck diameter of several loaded or dummy cartridges with an accurate micrometer. Subtract 0.001_ from the smallest average measurement to account for spring back and achieve a proper press fit for the bullet.

Alternatively, measure the neck wall thickness of the cartridge cases and calculate the neck diameter of a loaded cartridge by doubling this measurement and adding the bullet diameter. Again, subtract 0.001_ from this figure to determine the bushing size.

Considerations for Uniform Neck Wall Thickness

These methods are most effective when cases have uniform neck wall thickness or have been neck turned. If the neck wall thickness varies significantly, it may be necessary to choose a slightly smaller bushing size and then use a size button in the die to determine the final inside neck diameter.
