Hornady American Whitetail 243 Winchester 100 Grain InterLock SPBT Ammunition - 20 Rounds

The Hornady American Whitetail 243 Winchester 100 grain ammunition is purpose-built for deer hunters who demand reliable, consistent performance when it matters most. Loaded with Hornady's InterLock bullets, this 20-round box delivers the terminal performance and accuracy that have made American Whitetail a go-to choice for taking medium-sized game in the 50–300 pound range. Whether you're hunting from a stand in October or glassing a ridge in November, this ammo is engineered to deliver when you squeeze the trigger.

What sets InterLock bullets apart is their internal design: a raised ring inside the jacket that locks the core and jacket together during expansion. This keeps the bullet from shedding weight at the critical moment of impact, preserving energy transfer and ensuring the reliable, controlled expansion hunters depend on. The exposed lead tip promotes rapid initial expansion, while the secant ogive design—refined over generations of Hornady ballistics work—contributes to downrange consistency and accuracy out of modern rifles.

Hornady loads American Whitetail to conventional velocities, meaning these rounds cycle reliably in both bolt-action and semi-automatic platforms. The powder charge is matched to each load for optimum pressure and consistency, and every round uses quality Hornady cases and primers. That attention to component selection translates directly to tighter groups and predictable shot placement in the field—exactly what you need when a mature buck steps into an opening.
