The Redding Neck Expander Die is designed for reloading .45 Long Colt handgun cartridges. It gently bells the mouth of the cartridge to reduce wear on brass and support consistent seating of bullets. The die is built from quality steel and is backed by a company lifetime guarantee. Use is focused on neck sizing rather than full-length body sizing; observe the included guidance regarding case interchangeability.
Only the neck is sized as opposed to the body and shoulder. Because of this, do not interchange fired cases between different handguns of the same caliber.
