The Lee Precision Factory Crimp Die for .338 Win Mag and .338-06 A-Square is a precision reloading tool designed to improve accuracy and consistency in your handloads. Unlike standard seating dies, the Factory Crimp Die applies a firm, uniform crimp that holds the bullet securely in place—even on rounds with no crimp groove. This controlled pressure buildup ensures a more stable initial ignition and straighter pressure curve, translating to tighter shot groups and lower velocity spread across your shooting session.
The collet-based crimping system squeezes the case mouth evenly into the bullet's crimp groove, creating a mechanical lock that resists bullet setback during chambering and firing. Shooters who've switched to factory crimping often report noticeably improved accuracy, particularly in precision rifle work where consistency matters most. Whether you're loading for hunting or competition, this die works with any standard 7/8"-14 reloading press in your setup.
Lee's Factory Crimp Dies handle both standard crimping groove bullets and bullets without a groove, making them flexible for various bullet types and loads. Note that a shellholder is not included with the die, so ensure you have the correct holder for your cartridge before loading.
