Lee Full Length 3-Die Set 458 SOCOM

The Lee Full Length 3-Die Set is purpose-built for handloading the hard-hitting .458 SOCOM, a big-bore straight-walled cartridge designed around the AR-15 platform. This steel die set from Lee delivers the same sizing accuracy as Lee's carbide sets at a more economical price point, with the trade-off that cases must be lubricated before sizing.

The set includes three dies engineered specifically for the .458 SOCOM case: a Full Length Sizing Die with an integrated decapping unit that resizes fired cases back to factory dimensions while ejecting spent primers, a Micrometer Bullet Seating Die for precise, repeatable bullet seating depth, and a Powder Through Expanding Die that bells the case mouth and dispenses powder in a single smooth step. Each die is custom-machined to the exact case profile to prevent damage to the case neck during resizing.

Rounding out the package is a Universal Shell Holder, a Powder Dipper, and printed Instructions/Load Data so you can start loading .458 SOCOM right out of the box. The Full Length Sizing Die restores fired cases to SAAMI spec, the Powder Through Expanding Die streamlines the charging process for better shot-to-shot consistency, and the micrometer seating die lets you dial in seating depth with fine adjustments.

Finished in classic steel and sized for full-length .458 SOCOM rifle cases, this Lee die set is a straightforward, value-driven solution for handloaders working with this hard-hitting AR-compatible caliber.
