about halfway through last century i acquired a 94 win in .32 win spcl. being young, dumb, and full of ideas, and due to a situation where 32 win spcl ammo was unobtainium, i fed it 30-30.
case dimensions being close i got fire formed brass. accuracy was non existent.
at that time the Lyman manual had a conversion list in the back. using that i never got into trouble but with good head stamped brass available, that is the way to go.
I have been told that the 32 WS was popular in northern Canada during the 1st half of the 20th Century and maybe beyond because in a pinch 30-30 ammo could be safely fired in a 32 WS rifle with enough accuracy to harvest an animal for food.
