So... I bought some Winchester once fired cases awhile ago and the guy that I got them off tmbled them before sending in something that left a red, powdery dust inside the cases . It's proven to be a real bugger to get the dust out, I have to soak in Dawn dishwater and use a tube bristle brush to scrub the inside of the cases and then rinse and let dry on a rack for a few hours before I can resize them and get the spent primer out.
Am I being overly cautious or do I really need to worry about the red dust all and just reload them as is ?? My concern is that if that red dust is walnut she'll media, is it combustible and will it affect pressures if fired ???
 
Yep walnut shell dust. I would clean before resizing as best as possible to prevent getting the dies dirty or breaking the de-primer pin if they are badly filled with it. Have you tried compressed air? A sonic cleaner would work too if you wanted to invest in some case prep stuff. Cheers
 
It’ll likely be whatever polishing compound that’s used by manufacturer, Lyman most likely. I use crushed walnut from Princess Auto in my dry tumbler and it leaves no residue whatsoever.

You might try a rinse in 99% isopropyl alcohol or lacquer thinner, I use a couple different types of jewellers rouge bars on my bench buffing wheel and it leaves a similar residue that can be hard to remove.

Good GAWD, talk about overthinking things. Do you spend days thinking up random stuff to be concerned about?

Ignore the red dust and reload those cases.
 
Dump them in a bucket with warm water and a squirt of dawn dish soap and swirl them around in there for 10 min
Should get most of the dust out just need to dry the cases afterwards
 
Use an air compressor with a slim wand to clear them if you have one. The rouge won't hurt anything, just wipe the cases after.

Firing them will clean that stuff out nicely. Or, a wet tumble with pins and lemmeshine. I'd just load them and shoot them though. likely just dust from the tumbler media - wont hurt anything.

I bought some lyman red treated walnut years ago. Results were what you described. Used once and disposed of.
 
That Lyman's red treated dust is what finally pushed me to get into wet tumbling. But I used that stuff for a few years because money (or lack thereof).
 
I know many Reeloaders love shiny Casings but be wary of the "once Fired" advertised ones especially if they are shiny. Unfortunately there are Sellers which want to hide a flaw such as early indication of Case separation.

More often then not Casings for sale have been fired several times. Whom can proof they where not fired 6 times or more.
They only way to be reasonable sure a Rifle Casing is suitable for reloading is by employing the "Wire scratch method" which takes less then 2 Seconds.

Cheers
