Lee Breech Lock Collet Die .45-70 Government

Lee Breech Lock Collet Die for .45-70 Government

Precision Neck Sizing Technology

This specialized sizing die employs Lee's proven collet design, which uses a precision mandrel to gently squeeze the case neck into perfect alignment. The result is dramatically reduced runout—the wobble that can affect accuracy—without requiring any case lubricant.

Key Features

• Collet-based design minimizes case neck runout for improved accuracy
• No lubrication required, simplifying your reloading process
• Neck sizing only, preserving case dimensions and extending case life
• Breech Lock quick-change system for rapid die swaps on compatible Lee presses
• Integral threading works with any Lee Breech Lock-equipped reloading press

Why This Matters

For handloaders working with the venerable .45-70 Government cartridge, neck runout directly impacts shot-to-shot consistency. By sizing only the neck and maintaining precise alignment, you'll see tighter groups and more predictable performance downrange. The collet design is gentler on brass than conventional sizing methods, helping your cases last longer.

The Breech Lock system eliminates fumbling with die wrenches—simply lock and unlock your dies in seconds.
