  • The 7mm Weatherby Magnum (7mm Weath. Mag.) is a high-performance rifle cartridge developed by Roy Weatherby in 1962. This round was designed to offer higher velocities and flatter trajectories than other rounds of comparable caliber.

    The 7mm Weath. Mag. offers shorter barrel lengths, flatter trajectories and excellent ballistic coefficients due to its phenomenal velocity capabilities. This results in less drop and “drift” compared to other rounds when shooting at long distances, making it an ideal choice for competitive shooters looking for precision accuracy.

    For general hunting or varmint shooting purposes, the 7mm Weath. Mag provides plenty of power to quickly take down your target with ease while delivering impressive performance even at long distances. So if you are looking for a rifle round that provides superior accuracy and power the 7mm Weath. Mag should certainly be considered as an option.
