Never tested 200g bullets in .45 Colt (I use 250g RNFP or 255g SWC)... However, for light loads, Trail Boss is certainly the way to go.
A clinger. When guns are outlawed, only outlaws will have guns. Single Action .45 Colt (Sometimes improperly referred to by its alias as the .45 'Long' Colt or .45LC). Don't leave home without it. Ok.... the .44Spec is growing on me ... but the .45 Colt is still king.
