No. If you want BP velocities with smokeless powder I like 7-8 grains of Universal Clays under a 255gr cast lead boolit. If you like filling 45 Colt cases and making wonderful clouds of delightful blue smoke do it with FFFg black powder under the same boolit. When you want to give a 44 Mag shooter a history lesson about 21 grs of WW296 under a 300gr XTP should do the trick-but only in a Blackhawk or other stout action.
If you want to blow up a gun, injure yourself and quite possibly others then by all means fill a 45 Colt case with rifle powder. I've learned to treat BP and smokeless loads for the same cartridge as completely separate loads with completely different processes. They have little in common, sometimes I even use different brass.
