I was watching the History Channel program about the archeology of the Custer Battlefield at Little Big Horn. The archeologists were cleaning the old cases they found with an acid solution so they could read the head stamps and identify the primer stike markings. They were trying to ID the different weapons used by the Sioux in the battle! As it turns out, the Indians were using repeters (Henry's, Winchesters and Spencers) while the Troopers were using single shot Springfields!

The acid cleaned the cases, but it was obvious that it also thinned the old brass!

I would stick with tumbleing in corn cob or walnut!
