I went to the range this morning, took my .45s. I had some PMC and S&B ball ammo, and wanted to see how the various pistols handled them. S&B, which is usually cheaper on most websites, outshot PMC to a fare-thee-well. I use a lot of PMC, I like the brass for reloading purposes, and it outshoots everything except Federal ball.
S&B kicked it's collective butt. It's just good stuff, regardless of the inexpensive price, and it still uses Large Pistol primers, most of the CCI and Federal are now using SP primers, which cause headaches sorting the stuff. All four pistols I shot this morning favored the S&B heavily, and the two pistols I left at home have shown the same tendencies, they like it, too.
If you haven't tried it, it's worth the cost of a box or two, to see how it shoots in your pistols.
