Lee Precision 90575 Pacesetter 3-Die Set 300 Blackout

The Lee Precision 90575 Pacesetter 3-Die Set for 300 Blackout gives you a complete, affordable foundation for reloading subsonic rounds or match-grade .300 BLK ammunition. This three-die rifle set includes everything you need to size, seat, and crimp in one compact package—no hunting for individual dies or compatibility headaches. Whether you're handloading for a suppressed AR pistol, precision rifle, or subsonic hunting loads, Lee's Pacesetter series delivers the core tools without unnecessary complexity or expense.

Each die in this set has been machine-honed for smooth operation and consistent performance through thousands of cycles. The full-length sizing die ensures proper case dimensions for reliable feeding and extraction; the easy-adjust dead-length seater gives you straightforward control over bullet seating depth; and the factory crimp die finishes the job with secure, uniform crimps across your batch. For a cartridge like .300 Blackout—where consistency matters for both function and accuracy—these three dies handle the essential work.

The set ships with a universal shellholder, a powder dipper for quick charge estimates, printed load data to get you started immediately, and a red plastic storage box to keep your dies organized and protected. This is the no-nonsense reloader's choice: proven Lee engineering, three essential dies, and the accessories you actually need to begin working up loads the same day your set arrives.
