The occasional 45 Colt revolver, break barrel shotty, and 30-30 is all fine and good but have you cleaned black powder residue out of anything designed after 1890?

I don't know why this article choose pictures of modern casings for this article, I definitely wasnt arguing for the use in modern cartridges. I for one would only use black powder in firearms designed for it. They make some sweet black powder rifles nowdays.
I agree.
And those rifles are absolutely worth learning to use and and worth learning to make powder for.
It's relativity easy to do and a lot of fun.
