"...for loading .380 Auto ammo?"

Per the OP, these are .358" for 38 Special (and, possiby a +P or 357 Magnum?) loads.

In my experience cast .358" bullets don't usually play well in most 380acp or 9mm applications. I guess you could run them through a sizing die, but...

Cheers!

P.S. The ones I just got are coated, so..... Nope.
