The Lee Factory Crimp Rifle Die, Limited Production, for .338 ARC (brand part no. 92171) applies a secure post-seating crimp to help bullets stay put under the pressure and recoil of firing. As a limited production item, it’s built to the specific dimensions of the .338 ARC, a purpose-built AR-platform big-bore cartridge that benefits from a firm crimp for reliable function in semi-auto rifles. Adding this die to your press setup as a final station takes bullet retention out of the list of variables when developing a load, which matters when consistent crimp pressure affects both accuracy and cycling reliability.
