Mm Remington Magnum

The 6.5mm Remington Magnum was introduced in 1966 for the Model 600 carbine. The 6.5mm Remington Magnum is the .350 Remington Magnum case necked down to 6.5mm. As originally introduced, the Model 600 carbine had an 18.5-inch barrel. The later 660 carbine had a 20-inch barrel. Neither of these barrel lengths allowed the cartridge to fully develop its velocity potential.

The 6.5mm Remington Magnum was also chambered in Remington's Model 700 rifle with a 24-inch barrel. For a short time Ruger also produced Model 77s for this cartridge. At the present time no factory rifle is currently made for the 6.5mm Remington Magnum.

While intended to compete with the .270 Winchester, the 6.5mm Remington Magnum was handicapped by both the short barrels of the carbines and short magazines in the rifles. When chambered in a rifle that permits seating the bullets further out, one can attain .270 Winchester performance with comparable bullet weights.

The current Maximum Average Pressure for the 6.5mm Remington Magnum is 65,000 P.S.I.
