I like to tumble the brass before sizing... especially range brass to clean it before messing up my dies ...scratching. I spray it with the one shot and then let it dry... size it then a quick 15 minute tumble to get the lube off the brass. Last night was a bit more humid and warmer than what it has been lately... I must of rushed it a bit before it dried. I used to use RCBS lube and pad but found that the one shot was quicker and easier to apply. I guess I found out quicker and easier isn't the best way to go.
