Current Rifle Cartridges
8mm Remington Magnum
The huge 8mm Remington Magnum
was introduced in 1978 for the Model
700 (BDL) bolt-action rifles.
The cartridge is based on the 375 H&H
cartridge, blowing out the case for
more powder and widening the mouth
to accept 8mm; however, it will work
in a standard action rifle, which  is
unusual for a belted magnum of its
large size.
The cartridge puts out up to 4,150 foot
pounds of  energy, with a 200 grain
projectile able to travel at over 3,000
feet per second.
