Lee Factory Crimp Die for .270 Winchester Short Magnum
Lee's factory crimp die for .270 WSM firmly seats bullets for improved accuracy. A firm crimp raises pressure buildup, creating uniform pressure curves and reduced velocity variation.
Lee Factory Crimp Die for .270 Winchester Short Magnum
The Lee Factory Crimp Die represents a straightforward approach to one of reloading's most important steps: securing the bullet firmly in the case.
How It Works
This die crimps the bullet in place with greater force than conventional seating dies alone. The principle is simple but effective: a firm crimp prevents bullet movement during the pressure curve, which means pressure must build to a higher level before the bullet begins to shift. This creates a more uniform pressure curve throughout the firing sequence.
Performance Benefits
- Improved Accuracy: Tests show that even bullets without a crimp groove shoot more accurately when firmly crimped
- Consistent Velocity: Higher initial pressure ensures less velocity variation from shot to shot
- Uniform Pressure Curve: The firm crimp creates more predictable ballistic performance
Why This Matters
For handloaders seeking to wring maximum accuracy from their .270 WSM loads, the factory crimp die is an essential tool. Whether you're loading match ammunition or hunting rounds, the consistency gained from proper crimping translates directly to tighter groups and more reliable performance downrange.
