6.5-300 Weatherby Magnum Ladedaten

Introduced in 2016, the 6.5-300 Weatherby Magnum is one of the most recent and remarkable additions to the storied Weatherby Magnum family. It was developed by necking down the powerful .300 Weatherby Magnum case to accept 6.5mm (.264 caliber) projectiles, resulting in what was then the fastest commercially available 6.5mm cartridge on the market. The cartridge is the brainchild of legendary rifle and cartridge manufacturer Roy Weatherby’s legacy, showcasing the company's signature approach of high velocity and flat trajectories. The 6.5–300 Weatherby Magnum quickly gained attention among long-range enthusiasts and big game hunters alike, moving the needle forward in ballistic performance for the 6.5mm bore diameter.

The 6.5-300 Weatherby Magnum was designed with a strong focus on long-range hunting and shooting applications. Its blazing velocities and flat shooting characteristics make it ideal for hunters and precision shooters seeking uncompromised downrange performance. The cartridge is particularly appealing for those who participate in long-range hunting situations, where holding point of aim at extended distances is critical. Its incredible velocity enables shooters to take advantage of advanced ballistic coefficients found in modern 6.5mm projectile designs, resulting in minimal wind drift and maximum retained energy at range. The cartridge's power and precision have also made it a favorite among competitive long-range shooters and reloaders looking for something beyond what traditional 6.5mm cartridges like the 6.5 Creedmoor or .260 Remington can offer.

When considering target species, the 6.5-300 Weatherby Magnum is remarkably versatile. Its high velocity and energy make it an excellent choice for medium to large game such as deer, antelope, sheep, goat, and even elk. The cartridge has enough power for ethical, clean kills at extended distances on North American game species, and is also popular among hunters pursuing similar-sized animals in Africa and Europe. However, due to the high velocity and sometimes lighter bullet construction favored for this caliber, careful bullet selection is important to ensure deep penetration and controlled expansion on tough or larger animals. Reloaders often select premium, bonded, or monolithic bullets for hunting big game with the 6.5-300 Weatherby Magnum to avoid excessive fragmentation and maximize terminal performance.

Typical bullet weights for the 6.5-300 Weatherby Magnum range from 127 to 140 grains, with some factory loads and handload recipes utilizing projectiles as light as 100 grains or as heavy as 150 grains. Most shooters gravitate towards the 127- to 142-grain spectrum, as these offer an ideal blend of ballistic coefficient, velocity, and energy for both hunting and long-range target shooting applications. The high case capacity of the .300 Weatherby Magnum parent case provides ample room for slow-burning powders favored by many reloaders, resulting in impressive muzzle velocities—often exceeding 3,300 feet per second with 140-grain bullets. This not only ensures a very flat trajectory but also produces significant recoil and accelerated barrel wear, factors that reloaders should consider when selecting components and setting up rifles for this high-performance cartridge. The 6.5-300 Weatherby Magnum stands out for its unique blend of speed, reach, and downrange energy, making it one of the most exciting options for those seeking extreme 6.5mm ballistics.
