Hornady Lock-N-Load Modified B Case 7mm PRC Rifle Brass

The Hornady Lock-N-Load Modified B Case is a single 7mm PRC reloading accessory engineered to work with the Hornady Lock-N-Load Overall Length Gauge (sold separately). This specially prepared brass case lets the handloader measure a bullet's seating depth relative to the rifling lands in a specific rifle chamber, providing a direct read on the bullet's relationship to the lands when developing a load.

The case is manufactured to SAAMI specifications with overall length held to SAAMI-accurate dimensions. The case head is threaded so it threads directly into the Lock-N-Load Overall Length Gauge, and the neck is 0.002" oversized to accept the intended bullet for accurate measurement of its relationship to the lands.

One (1) modified brass case is included. The Lock-N-Load Overall Length Gauge, bullets, and other reloading components are sold separately. This is a load development tool, not a cartridge or live ammunition component.
