The 6.5mm Remington Magnum is a centerfire rifle cartridge introduced by Remington Arms Company in 1966. It was designed for their Model 600 and later Model 660 rifles. The cartridge is based on a shortened .350 Remington Magnum case, necked down to accept a 6.5mm (0.264 inch) bullet. The 6.5mm Remington Magnum is known for its high velocity and flat trajectory, making it suitable for long-range shooting, including hunting and target shooting.
Typical bullet weights range from 120 to 140 grains, offering a balanced mix of velocity, energy, and ballistic performance. It is particularly effective for hunting medium to large game, such as deer and elk, providing a good combination of stopping power and manageable recoil.
While the 6.5mm Remington Magnum never achieved wide popularity, it is appreciated by enthusiasts for its performance characteristics, especially in environments where long-range accuracy is required.
