clean loaded ammo ?

[scamp62]

I finally got my very own M1 Garand !!! and with it I got a can of M2 ammo, but it has some tarnish and small amounts of green mold where the machine gun links had been, anybody out there know how to clean loaded ammo ? or do I just shoot it and then tumble the brass for an extended time.

just hit it with one of those green scotchbrite pads. A couple of swipes per round should do the job. Now if you have thousands then that is a different story.

I've dry tumbled loaded ammo. No problems. A little polishing compound made for brass into the tumbler and 15-20 minutes and done.

Umm "Green mold" is not mold. Green mold is oxidation of copper, ie RUST.

If there is any visible pitting or marring under the copper oxide, I wouldn't shoot the round as the brass has lost some of its copper and will be weakened in that area

The green oxidation is called verdigris. I second the use of a Scotchbrite pad. The use of some citric acid will help remove the corrosion and make the brass bling. A table spoon in a half gallon of water is plenty. You can get citric acid at Walmart in the food canning area. Besides looking for pits also beware of the brass turning pink. This is an indication of some of the zinc being depleted. This makes the brass very week and dangerous.

Dry tumbling is fine just don't leave it in for 24 hours. There is a group who think that tumbling reduces the imr npowder to flour and make the burnt rate mutch greater. Never found that to be true myself.

They should try running some stick powder through a blender, and they'll be shocked at how hard the granules are. However, I would never tumble ammo that is loaded for high accuracy. Dry tumbling pistol ammo is fine if you are into bling bling.
