The 8.5x63mm, also known as the 8.5x63mm Reb, is a high-power rifle cartridge developed primarily for hunting large game. It originated in Norway, and its design addresses the need for a cartridge that offers improved ballistic performance over the popular 8x57mm IS (8mm Mauser) and 30-06 Springfield cartridges.
The 8.5x63mm cartridge typically fires an 8.5mm diameter bullet, which corresponds to approximately .338 caliber in imperial measurements. Its larger case capacity allows for higher velocity and energy, making it well-suited for long-range shooting and delivering greater stopping power.
Use cases for the 8.5x63mm include hunting large game such as elk, moose, and bear, thanks to its high energy and effective terminal ballistics. It might also be used in precision shooting and certain tactical applications due to its long-range capabilities.
Overall, the 8.5x63mm is valued for its combination of power, accuracy, and range, making it a versatile choice for serious hunters and sharpshooters.
