Cleaning dirty LIVE rounds

edited April 2009 in Perry Shooter Competition Shooting and Reloading Forum
A buddy of mine just got hold of 308 rounds for a great price at a gun show. (Don't remember country of mfg. but not USA.) About 30% of the case rounds had some kind of calcified build-up on them. I told him to clean them by hand with steel wool (I guess) but he bought 2,000 rounds and wanted a quicker way to do it. He is thinking about cleaning them in his tumbler! (Again, I am talking about loaded ammunition!) I told him it wasn't safe, he disagreed. We agreed to let the forum decide. Can these rounds be safely cleaned faster than one-at-time? How? Is my buddy right or should I buy a life insurance policy on him?

As a seperate question, what causes that kind of build-up? Are they still safe to shoot?

Thanks.

    Do not tumble or vibrate - powder gets pounded to finer grain - burning faster - blowing up gun and shooter. Clean with a rag and Brasso.

    I've heard the no-no about tumbling live rounds. And yes, if you tumbled them forever and a day I agree it could be an issue.

    However I've tried it and chronographed the results. No issue. Same as before tumbling.

    Probably depends on the powder as well though, that's my caveat.

    The FACTORY gives live rounds a tumble before packaging. Rounds get vibrated when riding in the semi on there way from the factory to the store and in your truck/atv too, think about it.

    Where is this deposit located, what color, spots or large areas?
    One quick way is to give them a minute or 2 dunking in 25% vinegar/75% water followed by a rinse in clear water and drying. Follow that with a 30-60 minute tumble

    If I remember right Brasso is not good for brass. Causes it to crack.

    Zip Trim and a 3M pad, or scrubby sponge, not wet.

    Please provided PROOF of your statement and not just hearsay. Please show me 1 CONFIRMED case of what you state.

    Please confirm that the factories do not tumble the ammo or that it does not get vibrated will being transported on the highways or even half way around the globe when coming from other countries.

    Many many Bulls-Eye pistol shooters tumble their loaded ammo Believe me if one ever went off it would be wide spread Knowledge. Now with that said a large drum tumbler with only a small amount of polishing compound with a pointed rifle bullet May set off a primer. Never heard of it and if it did it would not have enough force to punch a hole in the drum. It is not in a chamber and pressure would be very small . I dont advise to throw loaded ammo in a fire but they just go "PUTT" and you are in more danger from the case then the bullet.

    If the cases chamber, shoot them and throw the brass away. If not rub them with steel wool until they do. Lee makes a drill type case spinner for this. Cases with heavy tarnish will never clean up as the tarnish is embedded in the brass. If you have to reload them really look them over for splits with a magnifing glass.

    Why not call one of the powder manf. and ask them if its ok to put loaded ammo in a tumbler or vibratory cleaner for about 3 hrs ? (longer if its extra dirty )

    Why do people worry what the outside of the brass looks like?

    I tumble my brass until it's pretty clean before I reload it then don't worry about it. Doesn't look like new ammo, but I don't really care if my ammo is all tarnishy.

    The same reason people do not rub their trucks paintjob with sandpaper. A gritty round can scratch your chamber.

    The same reason you should use a bore guide or coated cleaning rod when cleaning a gun. Once the damage is there it cannot be fixed (without alot of expense). You know the old saying about an ounce of prevention.

    Back when I lived in Little Rock I had access to the Remington ammo plant through a production manager there.
    We were able to do chrono and pressure testing on rounds after 48 hrs in a tumbler.
    Also microscopic exams of the powder.
    There was absolutely NO difference in any case.
    Many, many reloaders, me included tumble ammo after loading.
    If there was a problem with it, you would have heard by now.
    It is SAFE!
