Hornady Lock-N-Load 6.5x55 Modified Case B65x55 for O.A.L. Gauge

• Chamber-specific modified case: Made for 6.5x55 Swedish-family chambers, this case threads directly onto the Hornady Lock-N-Load O.A.L. Gauge so seating-depth measurements are taken from your rifle’s actual chamber rather than from a generic reference.
• Supports precise bullet seating setup: The modified case helps establish the bullet’s contact point with the rifling, making it easier to tune cartridge overall length for more consistent jump and more repeatable load development.
• Brass construction: The brass body gives the case the correct form and feel for chamber use while remaining practical for repeated measuring sessions at the loading bench.
• Built for the Lock-N-Load system: Designed to work with Hornady’s O.A.L. Gauge, it fits naturally into a reloading workflow centered on repeatable measurements and quick caliber-specific setup.
• Useful across several 6.5x55 variants: Compatibility with 6.5x55 SE, 6.5x55mm Swedish, 6.5x55 SKAN, 6.5x55 Krag, and 6.5x55mm Mauser makes it a practical choice for reloaders working with this cartridge family.

About the Lock-N-Load Series

Hornady Lock-N-Load is the company’s modular reloading system, built to make caliber changes and measurement tasks faster without giving up repeatability. Within Hornady’s lineup, the series covers presses, die bushings, gauges and case-preparation tools, giving handloaders a common system for both production and precision work. A defining feature is the Lock-N-Load bushing design, which lets tools and dies be installed and removed with minimal disruption to setup.

In the measuring category, the series is aimed at reloaders who want tighter control over variables that influence accuracy, especially bullet seating depth and case dimensions. The Lock-N-Load O.A.L. Gauge and its matching modified cases are part of that approach: they let the user measure from the rifle’s chamber and the chosen bullet rather than relying on nominal cartridge dimensions alone. This makes the series especially relevant for precision shooting, load tuning and rifles where small changes in bullet jump can affect results on target. The overall design philosophy is practical and bench-focused: straightforward tools, caliber-specific fit where needed, and compatibility across a broader Hornady reloading setup.

About the Hornady Lock-N-Load 6.5x55 Modified Case B65x55 for O.A.L. Gauge

The Hornady Lock-N-Load 6.5x55 Modified Case B65x55 is a caliber-specific measuring accessory for reloaders working with the 6.5x55 cartridge family. Its job is simple but important: it provides the correct interface between the chamber and the Hornady O.A.L. Gauge so the reloader can determine where a chosen bullet meets the rifling in a specific rifle. That information is then used to set seating depth with more control than a standard cartridge overall length figure can provide.

For practical load development, that matters because bullet tips vary, chambers vary, and the distance from bullet ogive to rifling often has a direct effect on consistency. By using a modified brass case matched to this chambering, the measuring process becomes more repeatable and more relevant to the rifle actually being loaded for. This is especially useful when tuning loads for hunting rifles or older sporting rifles chambered in 6.5x55 SE, 6.5x55mm Swedish and related variants.

The case is intended for bench use with the Hornady Lock-N-Load O.A.L. Gauge, where it helps establish a reliable starting point for seating-die adjustment. As part of a precision reloading routine, it reduces guesswork, speeds up caliber-specific setup and supports more systematic comparison between different bullets or seating depths. With its brass construction and compact 15.00 g weight, it is a straightforward tool, but one that plays a meaningful role in accurate ammunition setup.

About Hornady

Hornady Manufacturing was founded by Joyce Hornady in 1949 in Grand Island, Nebraska. The company remains family-owned and is still headquartered in Grand Island, Nebraska, United States. Hornady is known for producing bullets, ammunition, reloading tools and accessories, with reloading equipment forming an important part of its catalog.

Its reloading range includes presses, dies, powder measures, scales and case-preparation tools, giving the brand a strong position among handloaders who want one system for both loading and measurement tasks. The Lock-N-Load system, built around a bushing design for changing dies, reflects Hornady’s practical approach to faster setup and repeatable bench work. That background makes the company especially relevant in products like modified cases and gauges, where dimensional consistency and compatibility across a broader reloading system matter more than cosmetic features.
