Hi,
I fired my first blackpowder cartridge handloads yesterday and began cleaning immediately. I rinsed my cases, decapped them, then soaked them in hot water with some dawn dish soap. I then dried them and tumbled them. After maybe 12 hours they were shiny on the outside again but the primer pockets and the bottom of inside the cases still have black spots. I soaked them again today and they are in the tumbler again while I sleep.

Is it normal to not get every speck of blackpowder residue out? Will the life of these shells be cut short? Or am I concerned about nothing?
