Lee Precision 90924 Lead Hardness Test Kit - 3 Piece Multi-Caliber

The Lee Precision 90924 Lead Hardness Test Kit provides reloaders with accurate Brinell hardness testing for cast bullets and lead alloys. This professional-grade testing system eliminates guesswork when selecting appropriate bullet hardness for different velocities and applications.

What Makes This Different

Unlike basic hardness estimation methods, this kit delivers precise Brinell hardness numbers through controlled indentation testing. The system uses a standardized steel ball and calibrated force application to create measurable impressions in lead samples. Results correlate directly to industry hardness scales, enabling consistent alloy selection for optimal accuracy and barrel protection.

Key Features

• Complete 3-piece testing system with steel ball indenter and measurement tools
• Multi-caliber compatibility for testing various bullet diameters and lead samples
• Precision-machined components ensure repeatable test results
• Compact 0.68-pound design fits standard reloading bench setups
• Durable steel construction withstands repeated testing cycles
• Clear measurement scale for accurate hardness reading
• Professional-grade accuracy suitable for commercial bullet casting operations

Accurate hardness testing prevents common casting problems including leading, poor accuracy, and excessive barrel wear. Softer alloys work best for low-velocity applications like target shooting, while harder compositions suit high-velocity hunting and competition loads. The kit enables precise alloy adjustment through tin and antimony content modification, resulting in consistent bullet performance across different powder charges and velocities.
