View Full Version : Corncob stuck inside the empty case

I was going to use a different title, but thought that may offend too many people.

Anyway, tumbled a whole bunch of 9X19, and found some casings with the media stuck on the inside. It wasn't a static charge thing, because this never happened with the .45 ACP brass. These happened a lot on the MFS- stamped rounds, and when cleaning them out with a toothpick, I found the media to be stuck to something gummy inside:

Would you say that these are safe to use? I remember adding some polishing compound to the media, but I tumbled it for about 30 minutes before adding any brass, to try to distribute it throughout the media.

If those were once fired cases the were originally loaded with bullet sealer to prevent moisture intrusion. The stickiness attracts the corncob.

Just scrape out the cob and load 'em. If you want to you can use some acetone, (nail polish remover) to clean the sealant out or it will gradually wear out with repeated tumbling.

...........as above stated.............or you could get a tumbler that actually tumbles and some stainless steel media and you will never have this issue. Obviously it costs more initially but it actually works unlike the system you have.

And no, I don't sell the system.

Wait until you go cheap an' try some WalMart pet bedding cob an' spend some paperclip time getting it out of the cases and the primer pockets. That will make for a happy day.

Add a little lacquer thinner to your media.

Air compressor, old brass brush in an electric drill. Wear gloves. Or because I shoot such a light load and the power doesnít even fill ľ of the case I would just load them up and shoot them. I also donít weigh any charges using those cases. But if your charge does not fit in that category I would get the media out.

Lacquer thinner might damage your tumbler. Try some paint thinner in your media and tumble again. Tumble with lid off till the stuff evaporates.

Time to replace your tumbler meda maybe. I know mine gets very sticky after awile. When I empty the tumbler a lot of it is sticking to it.

And no one seems to understand this.

It is, isn't it....:dunno:

Some paint thinner in the media will probably get the stuff out. It's not a huge thing but if it was me I would retumble with some paint thinner in the media. If it's just a small batch just wipe them clean and load them. He is new. He doesn't know what is safe and isn't. He's just trying to be safe.

Rotary media separator and universal decapping die. Works wonders in getting media out of the case and flash hole. Unless you put so much polish or mineral spirits to make the media a soggy mess.

I'll try some acetone in there and a paper clip to scrape out the junk. I am sorry for asking so many questions; I have quite a few new reloading manuals, along with the highly-recommended ABCs book to learn as much as I can about the art of reloading.

The Lee universal decapping die and an extra pin are en route from Midway, as are some Nosler 135 gr. JHP bullets, as recommended by the guys over in the 10 ring.

I'm not loading up anything to take out OBL at 50 yds in one shot, but am trying to ensure that I will be creating safe loads to run through my G23 Gen2 and G27 Gen4 without blowing either one (or any body parts) up while at the range.

I hope to pass along this good information to others later on.

Thank you again, reloading crew!

The paper clip thing will get old quickly, after all, it's just 9mm brass.
If your going to manually scrape it out, try chucking a bore brush in a drill, wrap it in a cleaning patch, drizzle a little solvent on the patch and let the drill do the work.

I just load them and shoot them.

As long as they're not wet there's no problem.

Never say sorry!!:supergrin: You can never ask to many questions. The people here seem to love to help others.

A lot simpler to avoid the sad situation.

So true, but if you didnít.

That little bit of media is going to have no effect on your reloads. Unless you have more than a hundred like this, even brushing out the cases can't take that long.
Then, 9x19 brass is cheap. Toss 'em and be done with it. Why waste time and money on solvents and cleaning where it just doesn't matter.
For those who don't like to scrape media out of the primer pocket, get some REAL 20/40 corn and forget about it. Personally, long before I found 20/40, I just let the depriming pin knock out the media.
For some of us, we are NOT going to get out brass wet and can not even imagine wasting money on stainless media just to have "virgin" brass. Anything more than a simply wipe of the case exterior is more than sufficient and some of us are more interested in what will help up shoot better and not what will make things shiny.

Use walnut.

The sealant used on case mouths is asphalt. It sticks to anything. Paving crews and dump truck drivers use diesel fuel to clean it off tools and truck beds.

I remember those days. Kerosene worked too.

I disagree. My stainless steel system has paid for itself in less than 6 months. I don't clean my brass so it's shiny. I clean it because the cases load easier, the primer pockets are clean and easier to seat. Just makes sense.

I also disagree that crap in the case doesn't affect the load. I can't give a specific instance but think about it. Why would you want junk (uncombustables) in the case? You don't think that those things affect performance in some way? Sure doesn't make sense to me.

I've had this happen with either walnut or corncob when too much turtle wax was added to the media. I pretty much stopped adding it because of this. A glock brush / cleaning rod will likely remove all that stuck media...while you're sorting by headstamp. It's gonna be a long night for someone.
