Hornady 7060 Crimp-On Gas Checks 7mm (.284) 1000 Count Box

The Hornady 7060 Crimp-On Gas Checks provide essential protection for cast bullet shooters working with 7mm (.284 caliber) projectiles. These precision-manufactured copper cups prevent gas cutting and lead fouling while maintaining consistent accuracy across extended shooting sessions.

What Makes This Different

Hornady's crimp-on design creates a secure mechanical bond that won't separate during firing, unlike cheaper alternatives that rely solely on friction fit. The .010-inch thick copper construction withstands chamber pressures up to 65,000 PSI while the precisely formed cup geometry ensures uniform bullet base sealing. This manufacturing precision translates directly to improved downrange consistency compared to generic gas checks that often vary in thickness and fit.

Key Features

• Precision-formed copper construction prevents gas cutting and lead fouling
• Crimp-on attachment method ensures secure retention through firing cycle
• Compatible with all 7mm (.284 caliber) cast bullets from 120 to 175 grains
• Uniform .010-inch wall thickness maintains consistent bullet weight
• Factory-tested for pressures up to 65,000 PSI in magnum cartridges
• Bulk 1000-count packaging reduces per-unit cost for volume reloaders
• Quality control standards ensure less than 0.001-inch dimensional variance

Cast bullet enthusiasts shooting 7mm Remington Magnum, .280 Ackley Improved, and similar high-velocity cartridges rely on these gas checks to maintain barrel condition and accuracy. The copper material resists deformation under extreme pressures while creating an effective gas seal that prevents propellant gases from eroding the bullet base. Competitive shooters report consistent sub-MOA groups when using properly fitted gas checks with quality cast bullets.
