The 8mm-06  is a necked out
30-06 cartridge to except 8mm
projectiles.
30-06 projectiles are .308" diameter
vs. the  8mm at .323 " diameter or
.011" more in diameter then the
30-06.
I can't find any book that will tell
me who first  this developed the
wildcat.
These cartridges for sale, were made
from Remington 30-06 cases so the
head stamp will say  WCC 53, as
they are made from Winchester
Military brass made in 1953.
