The Redding Series A Full Length Die Set for Bottleneck Cases in .300 Win Mag gives you the precision tooling you need to load ammunition that chambers reliably in any standard SAAMI .300 Win Mag chamber. Built for serious hunters and competitive shooters who depend on consistent, headspace-correct rounds, this two-die set handles the complete full-length resizing and bullet seating process with the kind of precision Redding has earned over decades of reloading equipment manufacturing.
The full-length resizing die includes a decapping rod assembly with a neck expander button, sizing your fired cases back to spec while removing spent primers in one pass. The seating die features a built-in bullet guide and crimp ring with the proper seating plug for your cartridge, letting you seat and crimp in a single stroke—faster, more consistent than separate operations. Both dies thread into standard 7/8-14 die bodies, so they'll fit any compatible single-stage or progressive reloader.
Redding's manufacturing standards are baked into every set. Their dies are machined on Hardinge Super-Precision lathes that hold industry-leading tolerances, then heat-treated in atmospherically controlled furnaces to guarantee durability. Each die is hand-polished for smooth, flawless operation, undergoes final inspection, and is ultrasonically cleaned before shipping. You're not just buying a tool—you're buying peace of mind that comes with ammunition that fits your chamber right.
The packaging doubles as a cartridge loading block and storage box, with room for a spare decapping pin, hex wrench, and your shellholder, so you've got everything organized and close at hand on the bench.
