I always check using my "rule of thumb". I dig my thumbnail into the bullet. If I can make a significant gouge, its "soft", and I don't even think of using it in an autoloader.

A small sliver of a mark, and its ok for autopistols, generally.

And if its only a bright spot on the bullet, then its "hard" and loaded for appropriate use.

As long as your bullet/groove diameter ratio is right, hard cast works great for everything, except expansion. And since I don't expect, or want expansion from my cast slugs, that's just fine with me.
