A powerful cartridge like the 8mm Remington Magnum has its drawbacks. Like every other big game cartridge it presents a stout recoil. Since there are not many factory loads available, the 8mm Remington Magnum is often used by reloaders. They can use this cartridge to create powerful loads by handloading, while staying within the 448 MPa (65000 psi) SAAMI piezo pressure limit. Combined with bullets with jackets designed for magnum cartridge muzzle velocities, and barrels of 650 mm (25.6 in) or longer to promote high muzzle velocities, the 8mm Remington Magnum offers the flattest trajectory and best long range performance of the commercially available 8 mm rifle cartridges.
