Reloading for the 7.7x58mm Japanese Arisaka rifle demands precision dies that respect the cartridge's unique case geometry—and the RCBS Full Length Die Set delivers exactly that. This two-die set is purpose-built for handloaders working with the Arisaka's bottleneck case, combining a full-length sizer die and a bullet seater die to take fired brass from range to reload-ready in consistent, repeatable steps.
The full-length sizer die sizes the case body to SAAMI minimum specifications while simultaneously decapping and expanding the neck to accept a new projectile. The die incorporates vents that prevent the damage caused by trapped air and excessive lubricant buildup—details that matter when you're working with vintage military brass that may already show its age. Headspace is managed to minimum tolerance to ensure the case body length stays true through the sizing stroke, a critical safeguard for safe, accurate handloads.
The seater die includes a built-in roll crimper, so you're securing the bullet in place while seating it in one smooth operation. Both dies are threaded to the standard 7/8-inch-14 spec, making them compatible with any standard reloading press. If you're reviving original Arisaka rifles or simply appreciate the history and challenge of loading for these classic military cartridges, this die set gives you the control and consistency you need to produce safe, accurate ammunition.
