I don't recommend Titegroup with lead or moly-coated bullets unless you have no other choice. It has a very high nitroglycerine content, burns hotter than most other powders and creates more smoke with lead bullets than other powders. Some claim it causes more leading than other powders but I haven't confirmed that in my limited experience.
Billy Bullets are excellent in .45 acp. The coating must be slick because the last batch of 200 gr LSWCs were going 40-50 fps faster than regular hard cast lead bullets with the same powder charge, primers, and cases.
Powders I use with Billy Bullets include American Select, Winchester Super Target, and Vithavouri N-320.
