Frequently Asked Questions

What does a cartridge gauge actually do?

A cartridge gauge checks whether your finished ammunition meets SAAMI specifications for your rifle's chamber. It's a physical verification tool—you simply insert your completed round and verify it fits without binding or excessive headspace. If a round doesn't fit the gauge correctly, it won't fit your rifle safely either, so you catch problems before firing.

Is this gauge compatible with other reloading setups?

This gauge is designed for use with Hornady's Lock-N-Load system and other compatible Hornady cartridge gauge accessories. It is caliber-specific to .22-250 Remington, so it is not interchangeable with gauges for other calibers.

What's included?

This product is the cartridge gauge itself for .22-250 Remington. It integrates with existing Hornady Lock-N-Load components and reloading equipment you may already own.

Why do I need a .22-250 specific gauge?

The .22-250 Remington has specific chamber dimensions and bullet diameter (.224). A gauge must be caliber-specific to accurately verify that your cases have been sized correctly and your finished rounds will chamber in SAAMI-compliant rifles. Using a gauge for a different caliber will give you false readings.
