338 Winchester Magnum
Prototype / Experimental
338 Winchester Magnum
was introduced in 1958 for
the Winchester Model 70
"Alaskan" bolt-action rifle.
These  50 year old,
Prototype / Experimental
were made by Winchester,
by necking down the
"458 Winchester Magnum"
to 338 caliber, which is why
they were not head stamped.
Picture at left, with the
two cartridges shows a new
358 and the prototype with
no head stamp.
They have some cleaning to
be done,  as we leave them
in the original condition for
you to decide to clean them
(or not), with a little paint
