From my research, I've found that the 147gr loads are better performers, and are easier to shoot/less abusive on the gun. Gold Dots, Winchester Ranger Ts ect. are all good. I've always been partial to the Gold Dot myself.
From what I've read, their quality control can be questionable, and their bullets, with the exception of their all copper DPX, can prove unreliable when shot through more than just ballistic gel. Again I have no personal experience, but I take this from well documented tests of others.
