Lee 92416 Micrometer Full-Length 2-Die Set 257 Roberts

The Lee 92416 is a Micrometer Full-Length 2-Die Set built for handloaders working with the 257 Roberts rifle cartridge. This set pairs a Full-Length Sizing Die with a Micrometer Bullet Seating Die to handle both case resizing and exact, repeatable bullet seating in one package.

The micrometer-style adjuster on the seater die allows precise incremental adjustments to overall cartridge length, taking the guesswork out of seating bullets to a specific COAL. The full-length sizing die resizes fired 257 Roberts brass back to factory dimensions for reliable chambering and consistent neck tension from one loading session to the next.

The set ships complete with a Universal Shell Holder that threads into any standard reloading press, and the dies are packaged in a red hard plastic storage case to keep everything organized on the bench. This 2-die set gives 257 Roberts handloaders the core bench tooling needed for consistent, repeatable reloads.
