Lyman Split-Loc Die Locking Ring - 7/8"-14 Thread

The Lyman Split-Loc Die Locking Ring with 7/8"-14 thread is a precision reloading component designed to secure dies in a reloading press without damaging critical die threads. This die locking ring solves a fundamental problem that standard locking rings create: the risk of set screw contact with die threads, which can strip or deform the threaded surfaces and compromise the structural integrity of the die itself.

The split-lock design isolates the set screw from the die threads entirely, eliminating the possibility of thread damage during installation or removal. This engineering approach is particularly important for reloaders who run multiple calibers through the same press or who swap dies frequently—repeated contact between a set screw and die threads accelerates wear and can eventually render a die unusable. The 7/8"-14 thread specification is the standard diameter and pitch for most single-stage and progressive reloading presses, making this locking ring compatible with the majority of Lyman press models and many competing press designs that use this industry-standard thread size.

Reloaders serious about extending die life and maintaining consistent ammunition specifications benefit from upgrading to a split-lock design. Whether you're loading rifle or pistol rounds across multiple calibers, this locking ring protects your investment in quality dies by eliminating a common source of premature wear. The compact, lightweight construction means it adds no measurable weight or bulk to your reloading setup.

Lyman is a long-established manufacturer of reloading equipment, and this die locking ring reflects the precision manufacturing standards expected in the handloading community. The split-lock design has become the preferred standard among reloaders who prioritize die preservation and consistent press operation over time.
