    Worked in an ammo plant from 89 to 92 (where I got my scar).

    We made the brass shiny using cyanide salts bathes as a final brass case manufacturing operation, before priming stations and move to loading area. That was an approx 30 meters long electro-chemical surface treament operation. Brass get shiny / golden and corrosion free for years.

    You never tumble a primed case. That's not safety at work station.

    First you lost case dimensional, second you are at risk of damaging primer sealant and breaking primer mixure pellets so inducing muzzle time variation (defect), third you are at risk of individual primer explosion while tumbling therefore going to the loading machine with an already burned primer (defect).

    And at the end of the day, that failing cartridge might get a LEO or a Military killed in operation. Analyze "clic"+ Tap/Rack do often take too much time when bullets are incoming.

Lou murdica uses 36.7 grains of lt 30 in his 30 br but i can't get that much in my cases. Anyway, i dropped some h4198 into one of my cases up to a little above halfway up the neck. I then turned on my sonicare electric toothbrush and ran the back of the head slowly up and down the case. Those little kernels started settling down purty as you please. Powder level dropped down enough i could have added at least half a grain to the case. Didn't take about more than 10 to 15 seconds. Don't know if i'll ever use this procedure but it was an interesting experiment.
    use little tricler will shake the case then add pd.
