Between strings I decap the cases and drop them in a jug with dawn dish soap a little lemon shine and water. Every couple strings I give the jug a shake. A laundry jug with the spout pulled out has a nice big opening to use for this. When I get home i [pur the jug out in the yard come in and rinse in the jug and cases 2-3 times with hot tap water. Spread them out on a screen to dry. When dry I polish in a vibrator with corn cobs nu finish Iosso brass polish and some alcohol. When polished nice. I clean primer pockets and use a nylon brush to clean inside of cases, this is more to remove con cob residue. Then anneal if needed or due for. I normally anneal very other loading.
I do the water jug to soften the residue and keep it soft. when you get home shake the jug a few minutes and pour out. the water will be black. ( a second cap can heve holes drilled in it to make a strainer) The first rinse and shake will be a gray color with subsequent lighter in color.
I use 20-1 alloy most but 20 lb wont make many of the big bullets ( youll get around 13 to the pound)
