Hornady Crimp-On Gas Checks .270 cal 1000/ct

If you're casting .270 caliber bullets at home, Hornady crimp-on gas checks are a practical upgrade for serious handloaders. These small steel cups crimp securely to the base of cast lead bullets during the sizing process, creating a seal that protects the bullet base from gas erosion and deformation when fired. This modest addition to your casting workflow can measurably extend the accuracy and consistency of your handloaded ammunition, especially as velocities climb or you push tighter loads.

Gas checks work by redirecting hot powder gases away from the soft lead base during firing—a process that becomes increasingly valuable in magnum cartridges and high-velocity loads where bare lead bases can strip or deform under pressure. For .270 shooters working with cast bullets, adding gas checks is one of the most straightforward ways to improve reliability and performance without complex equipment changes.

Hornady's crimp-on gas checks are engineered to seat reliably during standard bullet sizing, so they integrate seamlessly into your existing reloading bench workflow. Each box contains 1,000 checks, giving you plenty for a full season of casting and reloading.

Frequently Asked Questions

What's the difference between crimp-on and swage-on gas checks?

Crimp-on gas checks (like these Hornady units) attach by crimping into a recess at the bullet base during sizing. They integrate into your standard reloading process without requiring specialized swaging equipment.

Do I need gas checks for all my cast bullet loads?

Gas checks are most beneficial for high-velocity loads and magnum cartridges where soft lead bases are exposed to severe pressure and heat. Many .270 casters use them routinely to protect accuracy and bullet integrity across all velocities.

Are these compatible with my sizing die?

Crimp-on gas checks seat during the standard bullet sizing process. Verify your sizing die is configured for gas checks, or consult Hornady's reloading manual for .270 cast bullet loads with this style of gas check.

How many reloads will 1,000 gas checks support?

One box of 1,000 checks supplies enough for 1,000 cast .270 bullets. If you cast and reload regularly, you'll likely use several boxes per season depending on your volume.
