Lee Precision 90039 Classic Bullet Sizing Kit .311 Caliber

The Lee Precision 90039 Classic Bullet Sizing Kit delivers precise .311 caliber bullet resizing for handloaders seeking consistent diameter control and improved accuracy. This comprehensive kit addresses common bullet sizing challenges that can affect accuracy and feeding reliability in firearms chambered for .311 diameter projectiles.

What Makes This Different

Unlike basic sizing dies that only resize the bullet nose, this complete kit includes both the sizing die and gas check seater for comprehensive bullet preparation. The hardened steel construction maintains dimensional accuracy through thousands of sizing operations. The kit's design accommodates both cast and swaged bullets, making it versatile for various reloading applications where .311 diameter consistency is critical.

Key Features

• Precision .311 caliber sizing die with hardened steel construction
• Integrated gas check seater for streamlined bullet preparation
• Compatible with cast lead, plated, and jacketed bullets
• Standard 7/8-14 thread pitch fits most reloading presses
• Includes detailed instructions for proper setup and operation
• Durable steel construction resists wear from repeated use
• Works with bullets from .308 to .315 diameter for downsizing

This sizing kit proves essential for handloaders working with surplus military bullets, cast bullets from various molds, or mixed lots where diameter consistency varies. The precise .311 sizing ensures proper fit in chambers and barrels designed for this diameter, particularly important for military surplus rifles and certain European cartridges. The gas check seating capability streamlines the process for high-velocity applications where gas checks prevent leading.
