The RCBS 470 Nitro Express Full Length Die Set 3.25" (Part Number R24601) is a specialized, two-die mechanical reloading set engineered to reshape fired brass and seat bullets to precise SAAMI chamber tolerances. Built specifically for the heavy-recoil .470 Nitro Express 3 ¼” bottleneck cartridge, this Safari Series set consists of a Full-Length Sizer Die (complete with an expander-decapping unit) and a Bullet Seater Die (complete with a bullet seater plug). Constructed from proprietary hardened steel to withstand extreme sizing pressures, the dies utilize the industry-standard 7/8"-14 thread size, allowing seamless compatibility with standard single-stage and heavy-duty reloading presses without requiring specialized oversized bushings.

Key Features

• Dual-Stray Tolerances: Sizing dies are engineered with tolerances twice as stringent as typical firearm chamber dimensions, ensuring smooth cycling and reliable chambering in double rifles.
• Proprietary Die Steel: The hardened steel construction prevents physical deformation under the extreme mechanical forces needed to size safari-class brass.
• Adjustable Expander-Decapping Assembly: Features a secure three-piece locking system that eliminates slippage, with a decapping pin that can be replaced independently if damaged.
• Knurled Die Bodies: Designed with fine knurling on the exterior surface to facilitate quick, non-slip manual adjustments during setup.
• Standard Thread Compatibility: Built with 7/8"-14 threads to fit standard presses, unlike other Safari Series dies for larger cartridges that require a 1-inch die body.

Who is the Rcbs 470 Nitro Express Full Length Die Set 3.25" for?

• Handloaders reloading .470 Nitro Express safari cartridges — requires the standard 7/8"-14 thread compatibility of this nitro express reloading die set to safely resize large-capacity 3.25-inch bottleneck cases using standard single-stage presses without needing special 1-inch press adapter bushings.
• Dangerous game hunters maintaining double rifle ammunition — relies on the 0.61 to 0.63 kg nitro express reloading die set to precisely size fired brass to SAAMI minimum dimensions, ensuring absolute cycling reliability in high-pressure hunting situations.

Less suitable for: reloading other .47-calibre ammunition sub-variants or different case lengths, as this die set is strictly calibrated for .470 Nitro Express 3.25" brass casings utilizing a .474-inch bullet diameter; users requiring different calibres should look for calibre-specific standard or custom sizing die sets designed for those exact dimensions. Additionally, it requires a separate purchase of a standard #46 shell holder to function.
