  • The 7.63 Mauser is a type of full-sized rifle round developed in Germany during World War I, and is still widely used today.

    The 7.63 Mauser utilizes a 130 grain full metal jacketed bullet that produces velocities over 2,200 feet per second at the muzzle with an energy level of 1,895 ft/lbs – making it a powerful and effective rifle round for intermediate-range engagements and even hunting medium sized game animals. The relatively low recoil also makes it suitable for use in semi-automatic platforms, greatly increasing its rate of fire compared to more traditional bolt action rifles chambered in similar calibers.

    Since its introduction in 1888, this cartridge has become one of the most widely used rifle rounds in the world – being adopted by numerous militaries and police forces around the globe as their standard service firearm’s cartridge of choice. It is also popular amongst civilian shooters who want a more powerful option than most conventional pistol cartridges while still remaining manageable enough to be used without too much difficulty or training requirements.
