.308 Norma Magnum
There exists slightly less than two cents
worth of difference in the performance of various .30 caliber magnum cartridges,
which might explain why we don't hear much about the Norma version anymore.
But it wasn't always that way. Back in 1960 when Norma started shipping unprimed
cases, chamber reamers, and chamber drawings to American gunsmiths, its future
looked bright.
At the same time the
.300 Weatherby
and .300 H&H were the only .30 caliber magnum cartridges available and
both were too long for the ship loads of cheap '98 Mauser and '03 Springfield
actions floating around during the golden age of mail order firearms. In
addition, Winchester's short magnums in
.338 and
.458 calibers
were beginning to take off down the path of success. So, Norma's short .30
caliber magnum fit right into the scheme of things. For awhile the Swedish
cartridges future looked promising, but then came the
.300 Winchester
Magnum.
Logically speaking, no reason exists for buying a rifle in .308 Norma Magnum
today. By the same token, there is no logical reason for the handloader who
already owns a rifle in .308 Norma Magnum to trade it away for another chambered
to one of the other .300 Magnum cartridges. Factory ammunition is available
from Norma, and in a pinch, .308 Norma Magnum cases can be made by
necking up a 7mm
Remington Magnum case or necking down
.338 Winchester
Magnum cases. Since cases formed in this manner will be a bit short in
overall length, perhaps the best way to come up with cases is to run virgin
.300 Winchester
Magnum brass through a .308 Norma Magnum full length resizing die and
trim them back to 2.560".
