Product Overview
The Hornady .300 Win Mag Modified Case is a precision‑machined tool designed for use with the Hornady OAL Gauge system, giving reloaders a consistent and repeatable way to measure true chamber dimensions and bullet seating depth. Manufactured to exact tolerances, it threads smoothly onto the gauge and aligns correctly within the chamber, ensuring accurate and reliable readings every time. Using a modified case that mirrors your rifle’s chamber allows you to determine optimal cartridge overall length and fine‑tune bullet jump with confidence. This leads to improved accuracy, reduced pressure variation and a more controlled load development process. Hornady’s machining quality ensures uniformity and durability, even with repeated use on the bench. Whether you’re developing loads for long‑range shooting, hunting or precision work, the A300M modified case provides a simple and effective method for gathering the data you need. It integrates seamlessly with Hornady’s broader measurement tools and supports a more precise, data‑driven approach to reloading.
