Lee 90905 Factory Crimp Die 375 Winchester

The Lee 90905 Factory Crimp Die is a single-die reloading tool purpose-built for the 375 Winchester cartridge. Part of Lee's renowned Factory Crimp Die series, it uses a precision collet to apply a firm, uniform rifle-type crimp at the case mouth, locking the bullet in place for improved accuracy, consistent neck tension, and reliable feeding - even on a cartridge that is notoriously difficult to crimp.

The Lee Factory Crimp Die solves that problem by pressing the case mouth uniformly around the bullet, gripping projectiles that have no cannelure just as easily as those that do. The collet action also helps prevent case buckling during the crimp, and trim length is not critical, making the die forgiving to set up and use even for reloaders who do not trim every case to the same length.

Constructed from steel and sold as a single die, the 90905 is intended to be added to an existing reloading press alongside the user's standard resizing and seating dies. It installs easily on any standard press and delivers the consistent, repeatable crimp pressure needed to tame one of the more challenging bottleneck rifle cartridges in the reloading world.
