  • The 375 Weatherby Magnum (375 Wby Mag) is a rifle cartridge developed by Roy Weatherby in the mid-1940s. It is a belted, bottlenecked cartridge with a bullet diameter of .375 inches (9.5mm) and a case length of 2.913 inches (74mm).

    The 375 Wby Mag is known for its high velocity and flat trajectory, making it a popular choice among long-range hunters and shooters. It is capable of firing heavy, high-BC bullets at extremely high velocities, resulting in excellent long-range accuracy and terminal ballistics.

    The cartridge is suitable for hunting a wide range of big game, from elk and moose to African plains game and dangerous game such as cape buffalo and elephant. However, due to the cartridge's high velocity and energy, it generates significant recoil, which can be challenging for some shooters to manage.

    The 375 Wby Mag is typically used in rifles with strong actions and heavy barrels to handle the high pressures generated by the cartridge. Overall, the 375 Wby Mag is considered a powerful and versatile cartridge for big game hunting and has a loyal following among hunters and shooters who value its performance and reliability.

    When aggregating the ballistic performance of 205 suitable bullets for this caliber, you get an average powder charge of 74.1gr | 4.8g , an average muzzle velocity (V0) of 2647fps | 807m/s , and an average muzzle energy (E0) of 5510 Joule.
