Redding Reloading Equipment
The Redding Series A Full Length Die Set for Bottleneck Cases .375 H&H Mag is the precision reloading die set built for handloaders who demand consistency and durability with one of hunting's most respected magnum cartridges. This two-die set pairs a full-length resizing die with a seating die, engineered to deliver SAAMI-spec ammunition that chambers reliably in any standard action. Whether you're handloading for a classic magnum rifle or a modern bolt gun, Redding's Series A dies give you the tight tolerances and long-term reliability that serious reloaders depend on.
Redding manufactures these dies from premium alloy steels machined on Hardinge Super-Precision lathes to hold some of the tightest tolerances in the industry. The resizing die features a decapping rod assembly with integrated neck expander button; the seating die includes a built-in bullet guide, crimp ring, and proper seating plug sized for .375 H&H Mag. All dies undergo controlled-atmosphere heat treatment to maintain dimensional stability and are hand-polished, inspected, and ultrasonically cleaned before packing. The result is a die set that will outlast decades of reloading and produce ammunition as consistent as your handloading technique allows.
Setup is straightforward: both dies use the industry-standard 7/8-14 threaded bodies that fit any compatible reloading press. The included die box doubles as a cartridge loading block and storage solution, with slots inside for your shellholder, spare decapping pin, and hex wrench. That attention to detail—from machining to packaging—is what separates Redding from commodity die manufacturers and why handloaders who shoot magnum rifle cartridges keep coming back.

Yes. Redding Series A dies are designed to produce ammunition that properly fits any standard SAAMI-spec .375 H&H Mag chamber, regardless of your action type—whether it's a classic magnum bolt gun, double rifle, or other standard design.
The resizing die contains a decapping rod assembly with an integrated neck expander button that sizes the case back to factory dimensions and removes spent primers. The seating die includes a bullet guide, crimp ring, and seating plug that seats your bullet to proper depth and applies a crimp if desired.
Yes, a shellholder is required to operate these dies in a reloading press. The set does not include a shellholder, but the die box features a dedicated compartment to store one with your dies for convenient access.
All die components—the neck expander button, bullet guide, crimp ring, and seating plug—are engineered and sized specifically for .375 H&H Mag ammunition. The dies themselves use the universal 7/8-14 thread so they fit any compatible reloading press.
