- 154-grain Hornady InterLock bullet locks core and jacket together for controlled expansion
- Deep penetration and reliable mushrooming across a wide range of impact velocities
- 7mm Weatherby Magnum chambering optimized for Weatherby Mark V rifles
- Consistent, match-grade brass cases for reliable feeding and potential reloading
- 20 rounds per box — ideal for hunt-prep range sessions and field carry

Frequently Asked Questions
Is this ammunition compatible with all 7mm Weatherby Magnum rifles?
Yes — this ammunition is headstamped and loaded specifically for the 7mm Weatherby Magnum chambering and will function correctly in any rifle chambered for that cartridge, including the Weatherby Mark V and similar bolt-action platforms. Always verify your rifle's chamber markings before use, and never attempt to fire this round in a 7mm Remington Magnum or other similar-but-different chambering.
What makes the Hornady InterLock bullet suitable for big-game hunting?
The Hornady InterLock design features an internal locking ring that mechanically bonds the lead core to the copper jacket, preventing core-jacket separation even at the high impact velocities generated by the 7mm Weatherby Magnum. This results in deep, reliable penetration with controlled mushrooming — expanding to approximately 1.5–2x bullet diameter — making it highly effective on deer, elk, and similar-sized game out to 400+ yards.
Can the brass cases be reloaded after firing?
Yes. Weatherby uses quality Boxer-primed brass cases that are well-suited for reloading. After firing, cases can be full-length resized, reprimed, and reloaded using standard 7mm Weatherby Magnum reloading dies. Because the 7mm Weatherby Magnum operates at high pressures, inspect cases carefully for signs of wear, cracking, or primer pocket enlargement before reloading, and consult a current reloading manual for safe charge data.
