Hornady 284 Cal 7mm 139gr InterBond

The Hornady 284 Cal 7mm 139gr InterBond is a premium bonded-core bullet component engineered for handloaders seeking high ballistic efficiency, deep penetration, and reliable expansion in .284-caliber platforms. Weighing 139 gr with a .284-inch diameter, the 284 Cal 7mm 139gr InterBond features Hornady’s InterBond technology, bonding the lead core to the jacket to ensure over 90% weight retention and consistent terminal performance.

Utilizing a polymer-tip spire-point profile, the 284 Cal 7mm 139gr InterBond achieves a high G1 ballistic coefficient through its sleek secant ogive and boat-tail design. When loaded to typical velocities of 2,800–3,000 fps in cartridges like 7mm Remington Magnum or .284 Winchester, the bullet maintains flat trajectories and efficient energy transfer with minimal wind drift.

The internal construction of the 284 Cal 7mm 139gr InterBond includes Hornady’s proprietary core-jacket bonding, which prevents separation during impact and ensures deep penetration on game. Hunters report that the 284 Cal 7mm 139gr InterBond consistently delivers clean, channelled wound cavities and retained mass—even through bone and heavy muscle.

Optimized for twist rates between 1:9 and 1:10, the 284 Cal 7mm 139gr InterBond stabilizes well in bolt-action rifles and supports tight groupings at long range. The bullet also feeds reliably in magazine and single-shot platforms, thanks to a well-balanced design that combines aerodynamic form with practical riflesetting.

Manufactured in Grand Island, Nebraska, the Hornady 284 Cal 7mm 139gr InterBond is sold as a bullet component and requires matching brass, powder, and primers. With rigorous quality control over jacket concentricity, tip alignment, and bonding integrity, the 284 Cal 7mm 139gr InterBond stands as a top-tier option for precision hunting and handloading in the 7mm cartridge class.
