I run Blazer Brass for practice, training, and IPSC/IDPA. It's a lot cleaner than WWB in my 1911's. I did recently get a box that had multiple FTF's in my super-tight Wilsons but ran fine in a looser gun. Other than that one problem, I've probably shot well over 10,000 rounds of it and it's quite suitable for those purposes.
It's the cheapest hardball at the Wal-Marts in my area, too.
