I dug out some boxes of period Western .38 Special ammunition, just to show some of the variations in packaging and loads. A few dates to remember:
1944 - Western Cartridge Co became a division of Olin Industries. Very little commercial ammo production during the war, so this marking went into production in 1945.
1954 - Olin merged with Mathieson Chemical Corp.
1962 - Child Safety warning required by federal law.
Left column (top to bottom):
-Western 158 Grain standard velocity prewar box with nickel plated cases. No “Olin Industries” on back.
-Same load in a post-war box, where they crossed off “nickel plated cases”. Marked “division of Olin Industries” on back.
- Same load, where the box was printed without “nickel plated cases”. Still Olin Industries.
Center column:
-Western Super-X 150 grain high velocity post-war box with nickel plated cases. Marked “Olin Industries”.
- Same load, brasses cases. No patent #’s.
Right column:
-Western X (no Super) 158 grain standard velocity marked “Olin Mathieson Chemical Corporation” on back and no child safety warning.
- Same box with child safety warning.

Here’s a few other interesting boxes of ammo, just for fun. Prewar Western .357 and Winchester .38 Special and a post 1962 box of Western .357 AP ammo.
