Hornady 22 Hornet Modified Case
The Hornady 22 Hornet Modified Case is a precision reloading gauge insert designed for shooters who want to monitor bullet seating depth with the Hornady Lock-N-Load Gauge system. This modified case works as a reference tool, allowing you to visually and tactilely confirm that bullets are seated to the correct depth—a critical step in producing consistent, safe handloads. Whether you're fine-tuning loads for a 22 Hornet rifle or simply want another reference cartridge in your reloading workspace, this insert fits into the Lock-N-Load platform for quick, repeatable checks during the loading process.
Hornady's modified case system lets reloaders track bullet seating runout and depth without firing a round, which means you can catch seating inconsistencies before they affect accuracy or safety. The 22 Hornet insert is one of over 60 cartridge options available in the modified case lineup, giving handloaders flexibility across multiple calibers. If you work with cartridges not in Hornady's standard catalog, the company also offers custom modified cases—see the included instructions for details on how to request one.
Keep in mind that modified cases are inspection and setup tools only; they will not chamber in rifles with tight neck specifications, so they're strictly for bench use with your Lock-N-Load Gauge. This is essential equipment for serious reloaders who demand precision and repeatability in every round.
