High Performance Hornady Bullets

Millions of successful hunts have proven the accuracy and deadly knockdown power of the famous Hornady InterBond and GMX bullets that are loaded into the 257 Weatherby Custom rifle cartridge. These bullets deliver enough energy to successfully bring down deer, antelope and sheep.


Each cartridge is loaded to ensure optimal pressure, velocity and consistency, from lot to lot.

Highest Quality Cases

Much of the brass is made by Hornady. The rest is carefully selected for reliable feeding, corrosion resistance, hardness and the ability to withstand maximum chamber pressure.


Like the powder, each primer is carefully matched to individual loads, and specially selected for their ability to quickly, completely and reliably ignite the powder charge.



Hornady 257 Weatherby Magnum is loaded with InterBond or GMX bullets.
