Lee 90115 Case Length Gauge 7.7 Japanese w/ Shell Holder

The Lee 90115 Case Length Gauge is a two-piece reloading tool built specifically for the 7.7 Japanese cartridge, pairing a precision case length gauge with a matching shell holder in one convenient package. Machined from steel with a silver finish, this gauge firmly holds a single 7.7 Japanese (7.7mm) brass case in correct alignment so the reloader can quickly measure and trim fired cases to factory-spec length. It interfaces with the Lee Cutter/Lock Stud (sold separately) for repeatable case trimming and case-mouth squaring, helping handloaders achieve consistent case dimensions on this bottlenecked rifle cartridge.

Designed and made in the USA by Lee Precision, the 90115 is a simple, no-frills addition to any 7.7 Japanese reloading bench. The included shell holder accepts one casing at a time, streamlining case prep at the workbench. Whether you are working up handloads on vintage 7.7 Jap brass or fresh brass for sport shooting, this gauge delivers the consistent case-length control needed for reliable, accurate reloads.
