Product Overview
The Hornady Modified Case .300 Wby Mag is a precision‑machined tool designed for use with the Hornady Lock‑N‑Load O.A.L. Gauge. It allows reloaders to measure true bullet‑to‑rifling distance in their specific rifle chamber, providing the data needed to fine‑tune seating depth, control bullet jump, and build accurate, consistent ammunition. Each modified case is made from genuine Hornady brass and threaded at the base to attach securely to the O.A.L. Gauge. The case mouth is dimensioned to allow a projectile to slide freely, ensuring smooth, repeatable measurements without interference. For reloaders working with .300 Weatherby Magnum rifles, this tool removes guesswork and supports safe, precise load development. Whether you're tuning long‑range hunting loads or chasing maximum precision on the range, the HA300W modified case is an essential component of the Hornady measurement system.
