The Hornady Lock-N-Load 458 Lott Modified Case is a chambering-specific reloading accessory for use with the Hornady Lock-N-Load OAL (Overall Length) Gauge, sold separately. It is a once-fired .458 Lott case that has been drilled and threaded at the base to screw onto the OAL Gauge body. The reloader seats a bullet of their choice in the open neck, then carefully chambers the assembly in the rifle to establish the precise cartridge overall length at which the bullet engages the rifling lands. This measurement is the key reference point for setting optimum bullet seating depth in the .458 Lott — a heavy dangerous-game cartridge developed for reliable stopping power on Africa's largest game. Manufactured to SAAMI specifications, the modified case fits standard .458 Lott rifle chambers. It is an inert, reusable measuring tool and is not a loaded round, is not intended for firing, and requires no firearms certificate.
