Lee Full Length 3-die Set - .300wsm

The Lee Full Length 3-die Set for .300 WSM is purpose-built for handloaders who demand precision rifle ammunition tailored to their specific firearms and performance needs. Whether you're optimizing loads for long-range hunting, precision rifle competitions, or developing match-grade ammunition for a bolt-action rifle chambered in .300 Winchester Short Magnum, this three-die set provides the essential tools to resize, seat, and crimp brass with consistency and accuracy. Handloaders choose full-length sizing dies because they reset the entire case to factory dimensions, ensuring reliable feeding and chamber fit across different firearms—a critical advantage when working with magnum cartridges like the .300 WSM that demand tight tolerances.

This Lee Pacesetter set includes a full-length sizing die that restores case dimensions to SAAMI spec, a bullet seating die for precise bullet-to-ogive or case-mouth positioning, and a factory crimp die that applies consistent neck tension without marring the bullet jacket. The universal shell holder accommodates the .300 WSM case head size, while the included powder dipper and comprehensive load data enable immediate reloading session setup. Lee's three-die architecture eliminates the need for separate sizing and neck-sizing operations, streamlining your reloading bench workflow while maintaining the dimensional accuracy required for magnum rifle cartridges that generate higher pressures and tighter chamber tolerances.

Serious .300 WSM shooters—from competitive long-range hunters to precision rifle competitors—benefit most from this full-length sizing approach because it guarantees that each handloaded round will chamber consistently across multiple firearms or after cleaning and annealing cycles. The factory crimp die is especially valuable for magnum loads, as it maintains proper bullet grip in the case neck without the risk of over-crimping that can create pressure spikes. Compatible with standard single-stage or progressive reloading presses, this set delivers the accuracy foundation needed for sub-MOA rifle performance and reliable feeding in modern bolt-action platforms chambered for this powerful short-magnum cartridge.
