Lee Precision 90556 Ultimate Rifle 4 Die Set 243 Win

The Lee Precision Ultimate Rifle 4-Die Set for .243 Win gives handloaders the flexibility to work with brass from multiple sources and dial in the accuracy their rifle demands. This complete reloading die set handles everything from fired range brass to match-grade ammunition, making it an ideal choice whether you're building loads for a new rifle or fine-tuning rounds for an existing one.

The set's four-die approach separates the jobs so each one gets done right. The full-length resizing die restores fired brass to factory dimensions—essential if you're pooling cases from different firearms or need consistent sizing across a batch. The collet neck sizing die works on fire-formed brass without requiring case lube, and it's designed to preserve case life while maintaining the concentricity that translates to tighter groups. The Easy Adjust Dead Length bullet seating die removes the guesswork from seating depth, ensuring repeatable precision every time. Cap off the set with the Factory Crimp die, which applies uniform crimp pressure whether your bullets have a crimp groove or not, often resulting in improved velocity consistency and accuracy.

This is a working reloader's set: you get the shell holder, powder measure, and Lee's detailed load data organized by powder type so you can find the load you need fast. No separate purchases required to get started. Whether you're loading for competition, hunting, or keeping a favorite rifle supplied, the versatility built into this four-die setup means you're not locked into one approach.
