The 8mm Remington Magnum holds the distinction of being the most unsuccessful cartridge ever developed and introduced by Remington since World War II. Introduced in 1978 in the Model 700 BDL rifle, production in this caliber ceased around 1985 but was added to the list of options available from Remington's Custom Gun Shop in 1987. All of which is rather puzzling since the 8mm Remington Magnum seems a bit less ridiculous than the .338 Winchester Magnumfor use on deer size game and yet it should perform just as well on elk and moose. On the other hand, the .338 Magnumhad a 30 year head start, is short enough for medium length actions, and is available with heavier bullets. Perhaps we will never know the real reason why the Winchester cartridge did and the Remington cartridge didn't. Even though the 8mm Remington Magnum hasn't exactly set the woods afire with its popularity, one would have to look long and hard before coming up with a better cartridge for use on elk, moose, and larger African antelope. Bullet selection is quite critical with this cartridge since many are not designed and constructed to hold together at magnum impact velocities. 8mm bullets designed for smaller cartridges should be avoided in the 8mm Remington Magnum for any hunting applications.
