The Lee Factory Rifle Crimp Die, .243 WSSM (Lee part no. 90187) is a carbide factory crimp die built for Lee‘s single-stage and turret press lineup, sized specifically for .243 WSSM rifle cases. Its carbide sizing ring post-sizes the loaded round while the crimp is applied, so the finished cartridge chambers as freely as one straight from the factory instead of needing extra sizing passes. Because the crimp comes from squeezing the case mouth rather than relying on a cannelure, it works on a wide range of bullet styles, including jacketed bullets that don’t have a crimp groove cut into them at all. Crimp amount is set with a simple adjustment screw, so dialing in more or less bite on the case mouth takes seconds on the bench.
