Redding Series A Full Length Die Set for Bottleneck Cases .375 H&H Mag

The Redding Series A Full Length Die Set for Bottleneck Cases .375 H&H Mag is the precision reloading solution serious handloaders and match shooters depend on for the .375 Holland & Holland Magnum cartridge. Built for shooters who demand consistency across every round, this full-length die set ensures uniform case length, bullet seating depth, and primer pocket uniformity—critical variables that separate match-grade ammunition from factory loads.

The .375 H&H Mag's belted magnum design requires precisely engineered tooling, and Redding's Series A delivers the repeatability needed for hunting rifles and long-range applications where every shot counts. Redding's Series A die set features hardened steel construction with precision-ground internal dimensions to handle bottleneck magnum cases without dimensional drift. The full-length sizing die resizes the case body and shoulder while the decapping pin safely removes spent primers, preparing brass for repriming.

The seating die includes an interchangeable seating button and micrometer adjustable stem, allowing you to dial in exact bullet seating depth to within .001 inches—essential for optimizing velocity consistency and accuracy in magnum rifles. Many reloaders pair this die set with dedicated powder charging equipment for maximum control. The compact design fits standard single-stage and progressive presses, weighing 1.28 lbs and measuring 4.4 x 1.85 x 6 inches for easy storage and transport.
