Overview
Built for reloaders working with 400 Legend cartridges, this single die applies a rifle-style crimp through a collet design. It is intended for cases that can be difficult to crimp and can form a crimp even when bullets do not have a crimp groove. Lee notes that a firm crimp can help create a more uniform pressure curve and reduce velocity variation, which may be useful when consistency matters at the bench. This die is not carbide, so it is best considered a straightforward reloading tool for shooters who want controlled crimping in their load setup.

- The die is not carbide, which may matter if you prefer carbide construction in your reloading setup.
- It applies a firm rifle-style crimp; that can be useful for consistency, but it also adds an extra adjustment step to the loading process.
- Bullets do not need a crimp groove, but the strong collet action means setup should be handled carefully to avoid over-crimping.
