The Hornady Custom Grade New Dimension (CGND) .308 Winchester Full Length Sizing Die (MPN: 046359) is an individual, single rifle reloading die designed to resize fired cartridge brass back to factory SAAMI minimum dimensions while decapping spent primers in one operation. Built from polished tool steel and threaded to the standard 7/8"-14 thread pitch, it mounts into reloading presses from major manufacturers. It is engineered specifically for standard .308 Winchester cases and standard-dimension 7.62x51mm NATO brass, sizing the case body, shoulder, and neck to ensure reliable feeding and extraction across various firearm actions.

Key Features

• Full-Length Resizing & Decapping: Restores the case body, shoulder, and neck dimensions to factory SAAMI minimum specifications while removing spent primers in a single press stroke.
• Zip Spindle™ System: Utilises light, interrupted threads cut into the decapping spindle and spindle collet to prevent slippage while enabling rapid coarse adjustments and precise micro-adjustments.
• Elliptical Expander: Features a polished expander measuring .3065" that reduces friction and prevents brass stretching as it exits the case neck, maintaining neck-to-shoulder concentricity.
• Sure-Loc™ Lock Ring: Clamps around the 7/8"-14 die body threads using a split-ring design that tightens firmly without biting into or damaging the thread pitch.

Who is the Hornady 308 Win Full Length Die for?

• Handloaders reloading for semi-automatic platforms — Resizes fired .308 Winchester cases back down to minimum SAAMI dimensions across the body and shoulder to guarantee chambering reliability in tight semi-auto chambers using industry-standard 7/8"-14 thread pitch presses.
• Hunters and target shooters reloading across multiple rifles — Employs a polished .3065" elliptical expander to size the case neck for consistent 0.002" bullet tension, ensuring fired brass from different chambers reliably feeds, chambers, and extracts across any standard .308 Winchester rifle.

Less suitable for: Firearm chambers with altered shoulder geometry such as .308 Ackley Improved, larger .30-calibre cartridges like .30-06 Springfield and .300 Win Mag, or target shooters seeking custom neck tension beyond the fixed 0.002" threshold, who require a dedicated bushing-style neck sizing die. This non-carbide steel die also requires external case lubrication to prevent stuck cases.
