Lee Precision Factory Crimp Die 7mm STW / 7mm RUM

The Lee Precision Factory Crimp Die is a single-die reloading tool engineered specifically for the 7mm STW and 7mm RUM belted magnum cartridges. It threads onto any standard single-stage or turret reloading press using the common 7/8x14 thread pattern and serves as the final step after resizing and bullet seating, applying a consistent factory-style crimp on every loaded round.

Built around Lee's Factory Crimp design, this die crimps the bullet in place more firmly than any other reloading tool, and the higher start pressure it produces delivers a more uniform pressure curve and less velocity variation from shot to shot. An integrated carbide sizer post-sizes the case during the crimping stroke, guaranteeing that every round will chamber smoothly in your rifle. Sold as a single die, it is the ideal finishing step in any 7mm STW or 7mm RUM reloading setup.
