Area 419 Firearms Mandrel Sizing Kit 7mm - ZERO Die

The Area 419 Firearms Mandrel Sizing Kit in 7mm delivers precision-ground, full-length mandrels built for the brand's ZERO Sizing Die reloading system.

Each kit ships with four mandrels in .0005" neck-tension increments, giving the reloader the room to dial in bullet grip based on bullet diameter, case brand, and annealing practice. The mandrels drop into the ZERO die body to deliver smooth, concentric resizing and repeatable neck tension on match-grade 7mm handloads.

Sold as a caliber-specific expansion for an existing Area 419 ZERO Sizing Die, this 7mm mandrel kit is a cost-effective way to add another cartridge to a reloading bench without buying a complete second die.
