Lee Precision 90037 Classic Bullet Sizing Kit .308 Winchester

The Lee Precision 90037 Classic Bullet Sizing Kit provides precision bullet resizing capabilities for .308 Winchester cartridges, ensuring consistent bullet diameter and improved accuracy for handloaders. This complete sizing solution addresses common bullet diameter variations that can affect chamber fit and shooting performance.

What Makes This Different

Unlike basic sizing dies that only resize cases, this dedicated bullet sizing kit focuses exclusively on achieving uniform bullet diameter. The kit includes a precision-machined sizing die and push-through punch system that maintains bullet concentricity while reducing diameter variations to within 0.001 inches. The hardened steel construction withstands repeated use without dimensional changes, delivering consistent results across thousands of bullets.

Key Features

• Precision .308 caliber sizing die machined from hardened steel
• Push-through punch system maintains bullet concentricity
• Reduces bullet diameter variations to 0.001-inch tolerance
• Compatible with standard reloading presses and arbor systems
• Includes detailed sizing instructions and lubrication recommendations
• Works with cast lead, plated, and jacketed bullets up to 200 grains
• Durable construction rated for over 10,000 sizing operations

Bullet sizing becomes critical when working with cast bullets or mixed bullet lots where diameter consistency directly impacts accuracy potential. Competition shooters rely on uniform bullet dimensions to achieve sub-MOA groups, while hunters benefit from improved terminal performance through better chamber fit. The sizing process also removes minor surface imperfections that can affect bullet flight characteristics.
