The 300 Remington Ultra Magnum is a 7.62mm high-capacity beltless cartridge suitable for both large game hunting and long-range endeavors. The beltless construction was thought to allow more a accurate chambering as well as increase the lifespan of the case. That particular construction has however been shown to have minimal bearing on such parameters. It is one of the most powerful 30-caliber cartridges available, with magnificent velocities and hence reduced bullet drop, designed to handle the largest game on the North American continent.
