Or, if you want to load this weekend, just skip all that tumbling/fuss, and just wipe the cases with a soft cloth - maybe a micro-fibre cloth - to get the grit off them. Unless you are ejecting cases onto the ground, or a filthy bench top, there shoudn't be any grit to start with.
Then shoot today, load tonight, shoot tomorrow. Shoot, don't make jewelry.
I have a tumbler, and I use it to make nice, but if the brass I want to shoot tomorrow is dirty today, I just loads it. In forty years, I have yet to scratch the inside of a die.
