Lee Bullet Sizer Punch .373 – Lower Base for Precision Sizing of Cast Bullets

The Lee Bullet Sizer Punch .373 serves as the critical lower component in conjunction with Lee Precision’s bullet sizing dies, engineered specifically for cast projectiles requiring a final diameter of .373 inches. This precision-machined punch guides the bullet smoothly through the sizing die, ensuring uniform diameter reduction while preserving the integrity and shape of the cast lead bullet. Its design prevents deformation or damage to the bullet’s nose, which is essential for maintaining ballistic consistency and accuracy in metallic and semi-metallic reloading processes.

Compatibility and Application in Reloading

Optimized for handloaders who cast their own lead bullets, the Lee Bullet Sizer Punch .373 is indispensable for achieving exact caliber specifications, particularly for European or custom cartridges that utilize a .373" bullet diameter. This punch is compatible with standard single-stage and turret reloading presses, allowing for seamless integration into established reloading workflows. It is specifically tailored for use with cast lead bullets and is not recommended for jacketed or plated projectiles, ensuring optimal performance in traditional lead bullet sizing operations.

Key Features and Advantages

• Constructed from hardened tool steel to provide exceptional wear resistance and long service life under repetitive sizing cycles.
• Designed to avoid direct contact with the bullet’s tip, maintaining the projectile’s aerodynamic profile and preventing tip deformation.
• Engineered for compatibility with Lee Precision’s .373" Bullet Sizing Die (sold separately), forming a precise bullet sizing assembly.
• Ideal for precision cast bullet sizing in metallic and semi-metallic reloading applications, ensuring consistent bullet diameter and improved chamber fit.
• Enhances overall ballistic performance by producing bullets with uniform dimensions, critical for accuracy and safe chamber pressures.

The Lee Bullet Sizer Punch .373 is a fundamental tool for reloaders dedicated to producing high-quality, consistent cast bullets tailored to specific cartridge chambers. When paired with the corresponding sizing die, it forms a reliable and efficient system that guarantees precise bullet calibration, essential for competitive shooting, hunting, and ballistic testing.
