ou1954,
I don't know about the entire line but the Federal Champion ammo that I've examined from Walmart in 9mm and .45 ACP has plated bullets. A few strokes with a file should let you know, or if you have a bullet puller you can examine the base and see if it has exposed lead. A recovered bullet from shooting a steel plate target would also let you know. Watch out for bullets bouncing back though. I can't swear to it, but if I remember correctly the CCI Independence and Speer Lawman lines may also be using plated bullets. Federal, Speer and CCI are all owned by ATK so I imagine they share quite a few of the same components. The discount houses demand ammo at rock bottom prices and manufacturers are cutting corners as a result. The "Winchester Steel" and Hornady "whatever they're calling it steel" product lines are other example of this cost cutting.
Best Regards,
