Lee Factory Rifle Crimp Die .300 WSM

The Lee Factory Rifle Crimp Die for .300 WSM is a precision reloading die engineered to deliver factory-level ammunition consistency on demand. Equipped with a carbide sizer, this crimp die post-sizes rifle cartridges while simultaneously crimping the bullet, guaranteeing that every reloaded round will chamber freely and perform identically to factory-loaded ammunition. The .300 WSM specification positions this die for serious rifle reloaders working with this high-velocity short magnum cartridge.

Operation is straightforward: adjust the included screw to set your desired crimp depth, then run prepared cases through the die. The Lee Factory Rifle Crimp Die's crimping force is powerful enough to reliably crimp bullets regardless of whether they feature a cannelure—a critical advantage when sourcing component bullets from varied manufacturers or working with older military brass. The carbide sizing element ensures consistent neck tension across your entire lot, translating to improved velocity uniformity and tighter shot groupings compared to unsized or inconsistently crimped ammunition.

This die accommodates a wide range of bullet styles and jacket materials, making it versatile across hunting, long-range target work, and precision rifle applications where the .300 WSM excels. Whether you're loading for accuracy testing, field hunting, or maintaining ammunition inventory for dedicated .300 WSM rifles, the Lee Factory Rifle Crimp Die delivers repeatable results. The .300 WSM crimp die integrates seamlessly into standard progressive or single-stage press setups.
