Carbon removal

does someone have a simple method for removing the carbon build-up in cases? Thanks, Pete

I once had

a case cleaning system made by IOSSO if I remember correctly. It came with a bag to place the cases in while soaking. One then rinsed them in water as I recall. Anyone using this system?
 
Still do

use the IOSSO liquid system before I anneal my cases ( 5 fireings) , a bit messy/time consumeing but I think the benifits are worth it.
 
Pete,
There is a guy here in Michigan that is selling a ceramic media that works in a rotary tumbler. I have been using it for most of this year now with 223 Rem. and 308 Win. cases. It works well. A few things though, as I stated earlier you need a rotary tumbler. I have also found that if you dont clean your cases quickly ( 1 to 2 weeks) after firing the carbon does not come out as easy. Also dont use alot of the media. If you are getting cases clogged up with the media you are using way to much. I use 2 small handfulls of it and dont have many cases with media in them.
The kit consists of the ceramic media and a bottle of soap that you add 1 capfull to the tumbler. It does work very nicely. My process is to run the cases in a regular vibratory tumbler for an hour just to clean up the outside of the cases. Then I resize the cases and run them with the ceramic setup for about 4 to 6 hours. Then after I seperate the cases from the media and dry them, then I run them through the vibratoy tumbler for a few hours just to polish them up a bit. I know it sounds like a lot of work, but it really is not all that bad. The cases are clean inside and out including the primer pockets. You should see how dirty the water is when you dump it out after the ceramic media run. Here is his address, sorry I have forgotten his name. HTH

Because of the high shipping cost for other types of cleaning material and the short life I switched to ceramic several years ago. I do not use a reloaders type of polisher. I have been using the foot baths from the locale secondhand stores, I buy them for around five bucks each, they have a heating element also that does speed the cleaning process.

The media sizes comes in different shapes and sizes, no more throw aways sure makes for cheaper costs. :)
 
What is the point of trying to remove the carbon from the inside or the case? Does it affect the capacity of the case? Help improve accuracy? Just curious....
 
Simple Carbon Removal

Buy a jug of CLR at Wal-mart, grocery store, etc. Soak cases 5-10 minutes pure strength in CLR, run a nylon brush inside the necks one time while still soaking, then rinse thoroughly with clean water. Cases will look and load like new!
 
Just curious ...

Cleaning the inside of case necks has value in that it helps maintain the OD dimension with a seated bullet when your running real tight neck chambers. Some very good shooters, and I mean really good, have given up the chore and advertise that they have seen no differences on paper. The cleaning of the case interior has advocates on both sides of the isle. If you think it has value, makes you feel good, and increases confidence, by all means have at it. ;)

I think I have figured out that cases with less carbon built up on the inside of necks allow bullets to be seated at more consistent a seating depths and two, after annealing, there is often BIG chunks of carbon that come out of the inside of the cases. There are some who claim that they often get their best groups from fireforming new brass as long as it is close to the origional chamber size. One could infir that the carbonless interior may be, in part, responsible for this phenonima. Tennyrate, it can't be a good thing to continue building carbon inside a case as it isn't a good thing to build carbon inside a barrel. Don't know any of this except for the seating consistency issue.

Ultrasonic cleaner (Harbor Freight) and citric acid powder in water. Fast and effective. I rinse in a bath with a little baking soda after cleaning, then rinse with fresh water a few times. No problems in several years with this method.
 
So really one would be fine just to brush the neck of the case out then?
 
Wellllll

I have yet to see a brush that would conform to the body and inside base of the case. In adition, when one preloads a lot of cases like I do, one needs to find a way to make things a whole lot less labor intensive.
 
If you are using cases fitted, or turned with clearances of .0015, I would
not tumble cases in anything hard. When this is done, the mouth of the case is peened and actually has a small flange. You no longer have clearance.
may not affect a Saami chamber at all.
