Description

Hornady 416 Cal Gas Checks #7125

Hornady's crimp-on gas checks will improve the performance of your own cast bullets. The gas check crimps to the base of case lead bullets during size to seal gasses and guard against deformation. For bullet casters, Hornady gas checks are the only viable option.

Best Suited For

The Hornady .416 gas checks (#7125) are designed for:

  • Cast lead bullet reloaders using .416 caliber (.416") projectiles
  • Large-caliber rifle cartridges such as:
    • .416 Rigby
    • .416 Rem Mag
    • .416 Taylor (cast loads)
  • Shooters pushing moderate to high velocities with cast bullets
  • Reloaders wanting:
    • Reduced barrel leading
    • Improved accuracy
    • Better performance at higher pressures

👉 These are essential when working with heavy, large-caliber cast bullets, where gas cutting and base deformation become more severe.

When To Use It

Use these gas checks when:

  • Your cast bullets have a gas-check shank
  • You are loading .416 caliber cast bullets
  • You plan to shoot at:
    • Higher velocities (beyond typical low-speed cast loads)
    • Rifle-level pressures
  • You want to:
    • Prevent gas blow-by
    • Maintain bullet integrity and stability

Avoid using when:

  • Using jacketed bullets (not compatible)
  • Your bullets are plain-base (no shank)
  • Shooting low-velocity loads, where gas checks are unnecessary

FAQs

Q: Are gas checks necessary for .416 cast bullets?
A: Strongly recommended for higher velocity rifle loads, especially with heavy bullets.

Q: How are they installed?
A: They are pressed/crimped onto the bullet base during sizing using a sizing die.

Q: Can I use them on any .416 bullet?
A: Only on cast bullets with a gas-check shank.

Q: Do they increase velocity?
A: Not directly—but they allow higher velocity loads safely by preventing leading and gas cutting.

Q: Are they reusable?
A: No, they are single-use components.

Delivery and Compliance
