The Hornady Custom Grade New Dimension Seater Die #8 (Model 044108) is a dedicated metallic cartridge reloading die engineered for seating 7mm (.284 inch) projectiles into short-to-medium length cases. Machined with standard 7/8"-14 threads, it integrates into standard single-stage, turret, and progressive reloading presses. The die focuses on reducing radial bullet runout and ensuring consistent cartridge overall length (COAL) across short-action and short-magnum cartridge designs, including the 7mm-08 Remington, .284 Winchester, 7mm Winchester Short Magnum (7mm WSM), and 7mm Remington Short Action Ultra Magnum (7mm Rem SAUM).

• Floating Alignment Sleeve: Features an internal New Dimension sliding sleeve that pre-aligns the cartridge case neck, bullet, and seating stem before seating begins, substantially minimising radial runout.
• Sure-Loc Lock Ring: Uses a split-collar clamp with a hex screw to apply uniform 360-degree pressure around the 7/8"-14 outer threads without marring the die body.
• Finger-Adjustable Seater Plug: Retained by an internal O-ring to provide steady friction for precise fingertip adjustments to cartridge seating depth.
• Cartridge Compatibility Envelope: Profiled specifically for .284-calibre cases up to approximately 2.17-inch case lengths and 2.8-inch to 3.0-inch overall cartridge lengths.

Who is the Hornady Custom Grade 7mm Seating Die for?

• Australian deer hunters — Precision-seats 7mm projectiles into short-action 7mm-08 Remington brass on standard 7/8"-14 threaded presses, delivering the low-runout ammunition required for ethical shots in Victorian and NSW hunting environments.
• Australian F-Class and long-range target competitors — Aligns .284 Winchester match cartridges using a free-floating internal sleeve within standard 7/8"-14 press setups to maintain strictly uniform seating depth across high-volume precision handloads.

Less suitable for: Handloaders assembling full-length standard or magnum cartridges such as the 7mm Remington Magnum, .280 Remington, or 7mm PRC exceeding the ~2.17-inch case length envelope; these require longer-bodied 7mm seating dies to avoid bottoming out the die body.
