  • The .338 Winchester Magnum is a powerful centerfire rifle cartridge designed for hunting large and dangerous game, such as elk, moose, and bear. It was introduced in 1958 by Winchester Repeating Arms Company and has since become a popular choice among hunters and long-range shooters.

    The .338 Winchester Magnum has a bullet diameter of .338 inches and a case length of 2.5 inches. It is capable of firing bullets weighing between 200 and 250 grains at velocities ranging from 2,700 to 2,900 feet per second, depending on the load. This results in a high muzzle energy and a flat trajectory, making it an effective choice for long-range shooting.

    However, the .338 Winchester Magnum also generates a significant amount of recoil, which can make it difficult to shoot accurately for some people. It is also a relatively expensive cartridge to shoot, as the ammunition can be costly.

    When aggregating the ballistic performance of 180 suitable bullets for this caliber, you get an average powder charge of 57.6gr | 3.73g , an average muzzle velocity (V0) of 2447fps | 746m/s , and an average muzzle energy (E0) of 4508 Joule.
