If you reload 280 Ackley Improved and want dead-straight case alignment when checking your work with Hornady precision gauges, the Hornady A280AI Lock-N-Load Modified Case is purpose-built for that job. This isn't a cartridge to shoot—it's a modified case that threads onto Hornady's Lock-N-Load Precision gauge system, letting you verify chamber fit and headspace with confidence. Reloaders who demand tight tolerances and repeatability know that even small alignment errors throw off your measurements. That's where the engineering in these modified cases matters.
The case neck is machined to sit perfectly round and slightly opened at the mouth, so a standard bullet slides in concentrically without forcing or binding. That matters because any cocking or tilting changes how your gauge reads. The fine-thread attachment to the gauge itself keeps the case locked square to the gauge body, eliminating the guesswork and hand-fitting that comes with jury-rigged setups. You get consistent, reliable results every time you use it—which is what precision reloading demands.
This is one of those tools that seems simple until you understand why it exists: Hornady engineered it to remove variables from the measurement side of reloading. If you're already invested in Hornady Lock-N-Load gauges and 280 Ackley Improved brass, adding the right modified case to your bench setup is a natural move.
This A280AI modified case is designed to thread onto Hornady Lock-N-Load Precision gauges. Check your gauge documentation to confirm compatibility with your specific model.
This is a modified case for measurement and gauging purposes only—not a cartridge to load and fire.
The round, slightly opened neck allows a standard bullet to seat concentrically (straight and centered) without binding or cocking, ensuring your gauge readings are accurate and repeatable.
