Once again, I will state that I do not have pressure measuring equipment, so I do not feel comfortable developing loads that will have lower pressure than Black Powder loads and be safe to shoot in my antique S&W Top Break revolvers.

And cleaning up after shooting Black Powder does not have to be the huge chore so many think it is. I have posted before about my method of cleaning up after shooting Black Powder. It takes about 10 minutes to clean a revolver that has been fired with Black Powder, I leave no water behind, and water based Black Powder solvents are not as nasty and foul smelling as Smokeless powder cleaning solvents.
