Proudly made in the USA!InterLock® Bullets
InterLock® bullets feature exposed lead tips for controlled expansion and hard‑hitting terminal performance. Bullets used in American Whitetail® ammunition feature our pioneering secant ogive design and exclusive InterLock® ring — a raised ring inside the jacket that is embedded in the bullet’s core that keeps the core and jacket locked together during expansion to retain mass and energy.
Powders
Loaded to conventional velocities, powder is matched to each load for optimum pressure and consistency, ensuring each load is compatible with semi‑autos as well.

Like all Hornady® ammunition, our American Whitetail® rounds use the highest quality cases and primers available. Consistent components translate to consistent shooting in the field.
