Wow. A little aggressive about other member's methods much?
He's loading straight walled pistol cartridges. Odds are, his dies are carbide lined. Not likely to scratch those with a little dirt on the cases if he chooses to size/deprime prior to tumbling (to get the full benefit of ss media, you should deprime prior to tumbling anyways). The carbide dies negates the need for lubricant of any sort on his non bottle necked cases, so there is no need to leave any residue in the cases. Leaving cases dirty/unpolished is a PERSONAL PREFERENCE, not some golden rule of reloading. Any process that is safe and makes an individual feel better about their reloading process, is the right thing for that person to do. Some people LIKE shiny, factory new looking brass....get over it!
OK, rant done.
Stev32K, Your brass looks great
. I personally live in AZ, so I don't use extra methods to dry my brass in the summer. it goes on a towel in the driveway for an hour and is almost too hot to touch. in the winter, I sometimes use the compressor to blow out my rifle cases, but otherwise, an hour on the towel in the driveway gets 'em bone dry. I still tend to tumble one day, and load the next, just in case. I use a small amount of dish soap (whatever the wife has on hand), a 9mm case full of lemishine, and a gallon of COLD water. it works fine for me.
