Hornady Cam Lock Pilot .310 Silver - Fits 303 British/7.7 Japanese Steel (Model 390952)

The Hornady Cam Lock Pilot in .310 Silver is a precision case-trimming component built for reloaders working with 303 British and 7.7 Japanese rifle brass. This pilot pairs with either the Hornady Cam-Lock Case Trimmer or the original Hornady Case Trimmer to guide cases to the correct trim length, ensuring consistent case dimensions for reliable chamber fit and safe, uniform ammunition.

Hornady has engineered this pilot from high-quality materials designed to deliver years of trouble-free service. If you're trimming 303 British or 7.7 Japanese steel cases—whether you're loading for a vintage Enfield, a Japanese military rifle, or another chambering in this caliber family—this .310 Silver pilot is the wear-resistant sizing component your trimmer needs to work correctly.

Reloaders who demand accuracy know that case preparation directly affects final ammunition quality. Undersized or oversized cases cause feeding issues, pressure inconsistencies, and shortened brass life. The Hornady Cam Lock Pilot keeps your trimmer working at spec so every case comes out ready for the next loading stage.
