Lee Sizing Kit .339 Cast Bullet Reloader

Lee Sizing Kit for .339 Caliber Cast Bullets

The Lee Sizing Kit represents the most practical approach to preparing cast bullets for reliable, accurate shooting. This system streamlines what can otherwise be a tedious process into something manageable and repeatable.

Key Features

• Universal Compatibility: Standard 7/8x14 threads fit any single-stage or progressive reloading press
• Nose-First Design: Bullets feed through the sizing die nose-first, eliminating the need for special nose punches or adapters
• Automatic Gas Check Seating: Gas checks are seated and crimped in place during the sizing stroke—no separate steps required
• Bullet Capture Container: Sized bullets drop directly into the included container for organized, efficient workflow
• Caliber-Specific: Precisely sized for .339 diameter cast bullets

How It Works

Simply insert your cast bullet nose-first into the die, operate your press, and the sizing operation completes in a single stroke. The system handles gas check placement automatically, saving time and reducing handling errors.

What You Need to Know

Lee sizing lube is sold separately and is essential for smooth operation. The kit is designed for cast bullets and works best with proper lubrication to ensure consistent sizing and longevity of the die.

This is a straightforward, no-nonsense tool for serious reloaders who work with cast bullets regularly.
