The Redding .416 Weatherby Magnum Full Length 2-Die Set (MPN: 80492) is a precision handloading tool designed to resize fired brass cases and seat projectiles to factory SAAMI dimensions. Machined from high-grade alloy steel on precision lathes and heat-treated in atmospherically controlled furnaces, this Series D die set features industry-standard 7/8"-14 thread bodies to ensure compatibility with standard single-stage and turret reloading presses. It provides full-length case body resizing, shoulder setback, decapping, and controlled projectile seating with an integrated roll crimp for large-capacity dangerous-game ammunition.

Key Features

• Full-Length Resizing Die: Resizes the cartridge case body, resets the signature double-radiused shoulder, and decaps spent primers while expanding the neck via an integral expansion button.
• Bullet Seating Die with Built-In Crimp: Features an internal bullet guide and a built-in roll crimp ring designed to secure heavy .416 in (10.57 mm) projectiles against recoil displacement in magazine boxes.
• Sure-Lock Lock Rings: Uses cross-bolt split lock rings to maintain precise headspace calibration without marring the 7/8"-14 die threads.
• Precision Construction: Heat-treated and hand-polished internal surfaces minimize friction and prevent brass galling during heavy sizing operations.
• Included Accessories: Supplied in a storage box that doubles as a cartridge loading block, complete with a spare decapping pin and an Allen hex wrench.

Who is the Redding 416 Wby Weatherby Magnum Full Length Die Set for?

• Northern safari hunters targeting water buffalo and scrub bulls — requires absolute chambering reliability in bolt-action dangerous game rifles, which this full length reloading die set delivers by resetting fired cases to factory SAAMI headspace across standard 7/8"-14 press setups.
• Large-calibre sport shooters and dangerous game handloaders — provides precise projectile alignment and a built-in roll crimp ring to seat heavy 10.57 mm (.416 in) diameter bullets securely against heavy magnum recoil.

Less suitable for: Reloaders loading alternative .416-calibre cartridges such as .416 Rigby, .416 Ruger, or .416 Remington Magnum; these require dedicated full-length die sets tailored to their distinct case dimensions and shoulder angles.
