Proper Bushing Selection

To determine the correct neck bushing size for your reloading:

1. Measure the outside neck diameter of a loaded cartridge
2. Subtract .002" to .003" from that measurement
3. This allows for proper brass spring-back and consistent neck tension

This critical step ensures your ammunition performs at its best, with uniform bullet seating and reliable feeding. The slight clearance prevents excessive neck tension that can cause inconsistent velocities and group dispersion.

For the Serious Reloader

Whether you're preparing ammunition for long-range competition or precision rifle matches, this die set provides the control and consistency that separates good shooting from exceptional shooting.
