Lee 400 Legend Factory Crimp Die
Lee's collet-based factory crimp die applies powerful rifle-style crimps to 400 Legend cartridges. Forms crimp grooves on bullets without pre-existing grooves, improving accuracy through uniform pressure curves and reduced velocity variation.
Lee 400 Legend Factory Crimp Die
The Lee Factory Crimp Die represents a significant advancement in reloading technology, particularly for handloaders seeking to maximize accuracy and consistency in their ammunition.
How It Works
This die incorporates a collet mechanism that applies a true rifle-style crimp to your cartridges. Unlike conventional crimping methods, the collet's design is powerful enough to form a crimp groove directly into the bullet—no pre-existing crimp groove required.
Performance Benefits
Improved Accuracy: A firm crimp ensures that bullet movement is delayed until chamber pressure reaches optimal levels. This creates a more uniform pressure curve throughout the firing sequence, resulting in:
- Higher and more consistent starting pressure
- Reduced velocity variation from shot to shot
- Tighter shot groups downrange
Versatility: The collet's power means you can use standard bullets without crimping grooves, expanding your component options and potentially reducing costs.
Important Specifications
This die is not carbide, so standard cleaning procedures apply. It's designed specifically for 400 Legend cartridges and integrates seamlessly into any standard reloading press.
Whether you're a precision rifle competitor or a hunter demanding consistent performance, the Lee Factory Crimp Die transforms difficult-to-crimp cartridges into a straightforward reloading process.
