Among the hardest & best brass we've had was Lapua Brown Box.
You can see in the table below that it's alloy is high in zinc (Muntz Metal).
You can also see here that OP's observed softness of Federal makes sense.
And while Norma makes some of the sweetest cases ever made, it's not very hard, and for many it does not last well. I've seen that myself & gave up on Norma long ago.
Winchester is harder,, even than blue box Lapua today.
