I purchased a cheapo Harbor Freight dual canister rotary tumbler I think it was $59 plus I used a 20% coupon.  Bought some SS pins off Ebay.
I load my dirty cases into the tumblers, add a squirt of Lyman case cleaner and a pinch of citric acid. Turn the tumbler on for a couple of hours, rinse the cases with clean hot water and shake them out in a rolled up towel.
It's amazing how clean the cases come out. Even the primer pockets look spotless. I will never use any other way to clean cases again.

Get a Lee Universal depriming die, no dirty cases through your resizing die.

I do not resize my black powder cases, only expand the neck enough to finger seat the bullet.

I usually deprime at the range using one similar to this.

Well that clears things up pretty well. Thanks guys. Looks like I need to purchase more reloading equipment. By the way I shoot a Uberti 1885 in 32-20. Love the single shots.

following another post on here I recent purchased a cheap ultrasonic cleaner for my BP cases. Works a treat with some water, dish detergent and some vinegar. Have never bothered with smokeless cases just normally clean the necks with a solvent soaked patch as soon as they come out of the action.

Me either.
I think if you have to size then wiping the inside and outside of the neck may help .
I just wipe them over with a old rag of Ed’s red.
Or polish or such.
I can’t see myself throwing all my perfectly formed brass in a container and bashing them around for a few hrs.
The cleaning solution must get shot out with each shot in the bore as well.
I will own up to cleaning a couple of batches of brass before ..
About every three or four years I must forget.
But after cleaning 50 or a hundred cases with copious amounts of build up out of them by hand I am cured of such uncouth behaviour.

I mate said try my ultrasonic he says.
Cleans them good he said
Real easy.
Ha my ears haven’t recovered from that vibration squealing thing and took like 20 goes to clean out my dirty brass.

Bahh humbug to you shiny brass lovers.
I have watched some top tier benchrest shooters using jacketed but....they only wipe the outside and run a brush thou the neck cos they size maybe a thou for some neck tension to keep their bullets aligned.
Do this little black duck.
