Marking your brass . . .

I use the magic marker technique as well. Fast and cheap. I use different colours for different batches/times fired so I can tell them apart.

You might want to use a colour other than black if you go the marker route. One time I shot beside a guy that had done the same thing with the black marker as I. He was merrily picking up my brass as well. When I pointed out that some of it was mine, he said his were all marked so he could tell which were his. I laughed as I told him my were marked the exact same way. Luckily I had all Fed. brass and he had Win., but I could have led to some hard feelings. I switched to colours and haven't looked back....

As per the pic, after well over 24 hours in a high concentration of lime-green koolaid, the brass is still brass coloured. It's really clean (thanks to the citric acid), but not the slightest bit green.

Back to a marker.

I use Sharpie marker too....color the primer only to identify the load, and, like Levi, index the side of the brass on the high point of non-concentricity. (Hey, c'mon, that sounds like I'm edgicated:dancingbanana: )

'Course, thats for rifle rounds, who cares how a handgun shoots.:D
 
I just make sure everyone sees me lick my rounds before I load them up.This has a double benefit, no one picks up my brass, and I don't have to worry about weirdos striking up a conversation.

Ok, in responce to joe-nwt's post on the first page
(I'd copy it here, but it's huge) about the many different
color finishes you can obtain with various chemical
combinations. .
Where the he11 is one suppose to aquire chem's like that ?

I found that on a website, along time ago and have never tried any of the recipes. I just posted it for info.

If I were to start looking, I think I would start at laboratory suppliers, maybe a few of the chemicals might be found at the drugstore.

If you are thinking of trying some, please post the results here. I'm interested in the outcome, I just never seem to find time to try it myself.

marking

I needed various head stamps for bench work, boosted a bottle of my wifes nail polish works like a hot damm as I was doing multiple loads between tumbling.
 
Hey everyone, It's "Dig up an old dead thread night" so I thought I would dig this one up from the archives.

Actually, I was looking for a way to mark my weighed brass into groups so I can clean a bunch at once rather than 50 at a time on their own.

Anyone find out where to get some of the chemicals mentioned? If so did you color any of your cases? Pics?

Did anybody get Kool-Aid or other methods to work?

Thanks,
Richard

Chemicals

Don't ask your pharmacist for these oddball chemicals. We just don't have them. They don't have any medical uses and aren't carried.
Also, if we could get some, they would be pharmaceutical grade and horribly expensive. Once, I wanted an ounce of fuming nitric acid for a bluing solution and found that the minimum I could order was four, 1 litre bottles.
I asked a teacher friend to pinch me some from the school lab, and made a donation to some school project.
For years, that virulent anti-gunner Ann landers would publish a column just before Christmas, on how to soak rolled up newspapers in a chemical solution to make yule logs and said that the chemicals are available in any pharmacy. It used to drive me buggy.
