785 and 680 are long gone as per my last post. Winchester really trimmed down their powder lineup quite a few years ago. When you get to the old powders, yes some of them had a Hodgdon equivalent (like all of their current powders do), but some of them didn't.
231 and 760 are the only two left of the four that dixielandman has. Data is readily available in most reloading manuals for those two.
And if I didn't mention it before
...only use them if it is known that's what's in the cans. If it's an opened, partial can then it's hard to verify the contents.
