Description

A high-strength, heat-treated steel shell holder designed for the 7.62x39mm and 6.5 Grendel cartridge families. It features a universal snap-in design compatible with all major reloading presses, ensuring precise alignment for resizing and consistent primer seating.

The Redding #12 shell holder is specifically tailored for cases with a rim diameter of approximately .445″. While some manufacturers suggest using a #3 (6.5 Swede) or other “close” sizes, the #12 is machined to the exact tolerances of the 7.62x39mm rim to prevent the case from tilting during the resizing stroke.

This precision is critical because the 7.62x39mm case has a significant taper; any misalignment in the shell holder can lead to uneven shoulder bumping or crooked bullet seating. Like all Redding shell holders, the #12 is heat-treated to prevent the “claws” from stretching and is finished with a black oxide coating for superior corrosion resistance. The knurled exterior ensures easy installation even when working with lubricants.
