Lee Precision 90821 Factory Crimp Die 7mm Remington Magnum

The Lee Precision 90821 Factory Crimp Die delivers consistent bullet seating and reliable crimping for 7mm Remington Magnum cartridges. This specialized reloading tool applies uniform pressure to create factory-quality ammunition with improved accuracy and feeding reliability.

What Makes This Different

Unlike standard roll crimp dies that can distort case mouths, the Factory Crimp Die uses a collet system that applies radial pressure evenly around the bullet. This design maintains case neck concentricity while providing optimal bullet retention. The die works with any bullet type and eliminates the guesswork associated with traditional crimping methods, producing rounds that match factory ammunition specifications.

Key Features

• Collet-style crimping system prevents case mouth distortion
• Works with jacketed, lead, and plated bullets without adjustment
• Standard 7/8"-14 threading fits most reloading presses
• Heat-treated steel construction for long-term durability
• Includes detailed instructions and load data references
• Compatible with Lee Auto Disk and Pro Auto Disk powder measures
• Maintains factory ammunition overall length specifications

The Factory Crimp Die excels in applications requiring consistent ammunition performance. Hunters benefit from reliable feeding in bolt-action rifles, while competitive shooters achieve improved accuracy through uniform bullet seating depth. The die eliminates bullet setback during magazine feeding and creates ammunition that functions reliably in semi-automatic platforms chambered for 7mm Remington Magnum.
