Lee Factory Crimp Die for 7mm Express & .280 Remington
The Lee Factory Crimp Die solves one of reloading's most persistent challenges: achieving a firm, uniform crimp on difficult-to-crimp cartridges. This die uses a collet mechanism that applies a rifle-type crimp far more powerfully than conventional methods.
Key Features
- Collet-based crimping system applies a firm, consistent crimp that improves accuracy and reduces velocity variation
- Carbide sizer post-sizes your cartridge while crimping, ensuring every round chambers freely like factory ammunition
- Works with any bullet — even those without a crimp groove or cannelure, as the collet is powerful enough to form one
- Simple adjustment — just set the screw to your desired crimp level
- Wide compatibility — accommodates jacketed bullets and a broad range of ammunition types
Why Crimp Matters
A firm crimp does more than hold the bullet in place. It improves accuracy by reducing bullet movement during firing and creates a more uniform pressure curve, which translates to less velocity variation from shot to shot. This is especially valuable for precision rifle work and handloading for consistent performance.
The Bottom Line
If you reload for .280 Remington, .280 Ackley, or 7mm Express, the Lee Factory Crimp Die transforms these notoriously difficult cartridges into a pleasure to reload. It's a straightforward, effective tool that delivers factory-quality results.
