Description

A high-quality, heat-treated steel shell holder designed for a specific family of cartridges, including the .30-378 and .338-378 Weatherby Magnums. Built to standard dimensions, it is compatible with all Redding presses and most other 7/8″-14 thread reloading presses.

The Redding #15 shell holder is manufactured to exacting standards to ensure it provides a perfectly square base for the cartridge. This is critical for maintaining concentricity and ensuring that the primer is seated at a consistent depth. The outside of the shell holder features a knurled surface, making it easy to grip and swap out, even with oily fingers.

Unlike some “universal” brands that may have slightly loose fits, Redding’s internal dimensions are tailored to minimize “slop.” This ensures that the case remains vertical throughout the press stroke, which is essential when working with the large, high-pressure magnum cases this specific holder is designed for.
