Hornady 7140 Crimp-On Gas Checks for 45 Cal Cast Bullets - 1000 Count Box

If you're casting your own .45 caliber bullets, Hornady crimp-on gas checks are a straightforward way to improve performance and barrel life. These copper checks seat onto the base of cast bullets, protecting them from deformation caused by hot propellant gases and helping reduce the lead fouling that builds up in your barrel over time. A 1000-count box gives serious reloaders enough checks for a solid shooting season without frequent reorders.

Gas checks aren't required for every cast-bullet load, but they're especially valuable if you're pushing velocity or working with softer alloy bullets. By sealing the base, they help maintain consistent bullet integrity and can extend the time between barrel cleanings—a real benefit when you're running high volumes downrange or hunting in the field where barrel maintenance isn't always convenient.

Hornady's reputation in the reloading space rests on quality control and consistency, and these checks reflect that standard. Whether you're fine-tuning loads for hunting rifles, working up accurate loads at the range, or just looking to get more life out of your barrel, having a reliable supply of gas checks on hand makes sense.
