Seeking help – Caked-Up Ammo
« on: September 16, 2011, 12:49:19 PM »
Left a few stacked cardboard cases of Federal .45ACP in the shed. Although the cardboard packing boxes LOOKED ok, the packing box and box over the ammo itself were eaten/rotted from the inside.

It looks like something ate the cardboard, and left behind a hard cake around the rims that were sticking out of the plastic holder.  Ammo worked in S&W revolver, but with the back ¼ inch or so and in particular the extraction rim gunked, I doubt even scraping would get the ammo to function in a semi-auto.  Alcohol did not dissolve the gunk.

Whew, sorry to hear about your problem! Can we get a picture of one of the trays?

Sounds like you've got a 'paper mache' thing going on.  Are the primers covered with the gunk? 

You may have to use a non penetrating oil to soften the material after it soaks in, and even that makes me cringe to think about deactivating the primers.  Maybe test a few rounds by brushing a light coat of CLP from the case neck and up to the extraction rim.  Put them back into the tray and let them sit for a while.
