Removing “black” for case necks

[crittrgittr]

Is there a way to remove the black from a case neck after tumbling your brass? If this is a repeat could you please share the link?

My tumbler usually takes it off, what are you using for media? You might try some very fine steel wool.

Mainly corn cob.

You might try treating your media with some polishing compound of some sort. Ultrasonic and stainless pin cleaners also seem popular, but I have never tried them.

If you are referring to the black carbon on the outside of the neck, using 0000 steel wool is very quick and effective.

On the out side 0000 steel wool will take it off and polish the brass. If you're talking the inside, a case neck brush will usually work fine, but I don't worry about the inside as long as the brass has been cleaned.

Corn cob media is not my favorite cleans poorly and plugs up my 223 primer pockets horribly when I tumble the second time after sizing to remove the case lube. I switched to Zilla lizard litter available at Petco. My first tumble I usually let run 3-4 hours minimum but mostly let it go over night. The second tumble to remove lube maybe an hour.

The 0000 steal wool does work very well especially when used in conjunction with these Lee case trimmers
You order case trimmer cutter lock stud and the case length gauge shell holder for your caliber. Chuck it up in a drill spin the brass holding the 0000 steel wool against the case to clean it up works great is really the ticket for low volume shooters no need at all for a tumbler or sonic cleaner.

Thank you for the replies. Yes I'm referring to the outside of the case. Looks like I'll try some steel wool. I did add some polishing compound, but I've ran probably 5-6 loads since.

The faster you remove carbon, the easier it is to remove.
Soon as I get back from shooting, I deprime with a hand deprimer, swipe junk from primer pockets, wipe outside of necks with any carbon remover/cleaner, drop cases in vibratory cleaner. If you leave carbon on necks for too long, then you'll need steel wool.

morning, try liquid jewelers rouge in media in tumbler.

Krazy kloth works good to usually can get on amazon or ebay

I use the Wipe Out products.
The Wipe Out accelerator on a rifle patch and it cleans right off. It is very simple and fast.
Also works well in rifle bores.

I have the same problem with my brass. I use a Frankfort Arsenal vibrator with walnut media and a liquid additive (Bright Brass or Brass Bright) that goes into the media to enhance polish. With that said, I have a drill press, however a hand drill could be used to help with the process of getting the black off. Depending on what caliber I am using, say for 30-06 casings, I'll take a length of 5/16ths (.312 thousandths) oak dowel/hardwood dowel about 2 inches long, chuck the dowel up and take a piece of fine sandpaper, turn the drill on and sand the end of the dowel down until it fits inside of the neck on the case, just a slip-fit is what you are looking for. You want to make the taper on the dowel fairly long so that the case neck can get a tight grip inside of the case neck. I then will slip the case up the dowel, give it a slight tap, not too hard, and then spin the case with the drill. I use a product called "Nevrdull" polish ($10.00), comes in a blue can (Google it), it is woven cloth where you can pull pieces of the cloth out by hand and use it to clean the cases. A piece of Nevrdull, turn the drill on and while the case is being spun in the electric drill, or in my case the drill press, run the Nevrdull over the case neck. I've found that faster spinning speed helps to get the cases clean faster, pretty simple do to. Making the wooden arbor is really simple to make, and takes but a little time to do. If you want to hold the case by the rim, Sinclair makes a "Neck Turning Case Holder'" for around $15.00, but they are case specific with different case holders, and you need to get the right holder for the case size you are polishing. My cases come out looking like new, or better than new with this method.
