I just picked up my second batch of 4800 rounds of 6.5 Swedish Blanks from J&G sales in Prescott Arizona. I can’t help myself! I have found head stamps all the way back to WWI and many different varieties of Norma and others.
My question is, does anyone know what chemical was causing the problems in the cardboard boxes that caused the discoloration? Some have a mild corrosion but most on the outer layers of each box seem to have this orange coating. It almost looks like copper has come to the surface of the brass. I was thinking that something mixed with Hydrogen peroxide might fix that. I’m sure it was from the boxes because there are four layers of 5 cartridges and the six in the middle have very little discoloration. It’s the ones around the edges that were mostly affected.
Of course I don’t want t do this for the collectible headstamps, just the one’s I will use for loading :)
Also, for those of you out there that like to use these for reloading . . . you can wet tumble them to clean them up and it will NOT affect the primers as they all have a foil seal. Sounds crazy but I have tested this process.
