Sure, they're worth reloading. If you have steel cases with Berdan primers, reloading will be a bit more difficult than if you have brass cases with Boxer primers.

I reload Wolf .45 ACP cases. They're steel, but have Boxer primers, which makes reloading easier. And, since they are made of steel, I regard them as being a little more suited for use with +P loads. I use a carbide siszing die with them, but you can't get carbide dies for bottlneck cases, so you may find that a resizing die will wear quicker if used to size steel cases. But these are MILD steel cases, much softer than your resizing die.....

Many people think that just because a case has Berdan priming that it is not reloadable. This is B.S. of the worst sort.
