Range of Sizes for Optimal Fit

Available in sizes from .185_ to .368_ in .001_ increments, this bushing caters to a wide range of reloading needs, allowing you to find the perfect fit for your cartridges.

Methods for Determining the Proper Bushing Size

There are several ways to determine the right bushing size:

• Measure the neck diameter of several loaded or dummy cartridges with an accurate micrometer, then subtract 0.001_ for the ideal size.
• Alternatively, measure the neck wall thickness of cartridge cases and add the bullet diameter to calculate the neck diameter of a loaded cartridge, again subtracting 0.001_.
• For new cases, measure the neck diameter after seating boat-tail bullets, or use a caliper to gauge neck wall thickness, though this may be less precise.

Considerations for Varied Neck Wall Thickness

If the neck wall thickness varies significantly, a smaller bushing than calculated might be necessary, followed by using a size button in the die for final inside neck diameter adjustments.
