Hornady Crimp-On Gas Checks in .30 Caliber, packaged 1,000 to the box (Hornady part no. 7070), are built for anyone casting their own bullets. During the sizing step, the gas check crimps onto the base of a cast lead bullet, sealing propellant gases at the base and protecting it from deformation as the bullet accelerates down the bore. Hornady positions its gas checks as the reliable choice for bullet casters, and a fresh check on every cast bullet helps keep leading and gas cutting to a minimum in rifle and pistol barrels alike.

Key Specifications

• Sized for .30 caliber cast bullets. matching the gas check to this bullet diameter.
• Crimps onto the bullet base during sizing. combining gas-check application with the normal sizing step.
• Seals propellant gas at the bullet base. reducing gas cutting and leading in the bore.
• Protects the base from deformation. as the bullet accelerates down the barrel under pressure.
• Built for cast lead bullets specifically. not needed on jacketed bullets, which do not require base protection from propellant gas.
• Suited to both rifle and pistol cast-bullet barrels. keeps leading and gas cutting to a minimum in either application.
• Applied fresh to each individual cast bullet. Hornady recommends a new check on every bullet rather than reusing one.
• Positioned by Hornady as the reliable choice for bullet casters. the brand’s own standard for consistent, repeatable gas-check performance.
• Packaged 1,000 per box. enough for high-volume cast-bullet reloaders to load without running out mid-session.
