Hornady 7140 Crimp-On Gas Checks .45 Cal 1000/Box

The Hornady 7140 Crimp-On Gas Checks are precision-made reloading components engineered for .45 caliber cast lead bullet shooters. These thin copper gas checks crimp onto the base of cast bullets during the sizing operation, sealing hot propellant gases behind the bullet and protecting the soft lead base from deformation that would otherwise smear and lead the bore.

Used by handloaders for both rifle and handgun cast bullet applications, Hornady gas checks are a proven solution for higher-pressure loads and hotter velocities where unprotected lead would foul the barrel rapidly. The positive crimp-on design expands at subsonic velocities to lock firmly onto the bullet base during sizing, delivering consistent seating shot after shot and the reliable sealing performance quality cast bullet reloading demands.

Each box contains 1000 gas checks, giving reloaders an ample supply for extended casting and sizing sessions across a wide range of .45 caliber cast bullet loads.
