The Norma 223 brass sucks giant balsacs. It's super soft. The new LC from Midway is pretty decent. One option: buy Berger .223 ammo loaded with Lapua brass.
Everyone in this thread needs to write Alpha and Peterson asking "Where 223?"
Is it any different from other Federal 223 brass? I've read lots of reports that Federal brass is soft. Haven't loaded enough of it myself to tell a difference.
To answer the OP - I've always had good luck with LC brass.
