Hornady Crimp-On Gas Checks .375 cal - 1000/ct

If you're casting bullets for handloads, Hornady Crimp-On Gas Checks in .375 caliber are a foundational component that can noticeably improve your cast bullet performance. These copper checks slip over the bullet base and crimp securely in place, protecting the lead from the heat and pressure of firing. Whether you're working up loads for big bore rifles or magnum pistols, gas checks are one of the best ways to push cast bullets safely to higher velocities without leading your bore.

The .375 size fits a wide range of popular cast bullet designs, making this 1000-count package a practical supply for serious reloaders. Each check is made from copper, chosen for its ability to withstand repeated firing cycles and provide a reliable seal against hot gases escaping past the bullet base. By containing that heat and pressure, the checks reduce the lead fouling that can accumulate in your barrel over time—keeping your bore cleaner and extending the life of your rifling.

These are the kind of components you'll want to keep in stock if you're committed to cast bullet reloading. Hornady's gas checks are manufactured to consistent quality standards, so you can reload with confidence knowing each bullet will perform as expected downrange.
