You're already using what's arguably the best powder for .45 Colt. Are you having a problem with it that's making you think of changing?
If you are about out of Unique and want to try a different powder, Hodgdon Universal is a good one to look at for the .45 Colt. Trail Boss is good, but not good enough for me to pay pound prices for a 9oz can. Since you mentioned cowboy, I'll assume you're not trying for the "Ruger Only" hot loadings.
