Had a buddy of mine ask me the other day if it would be alright to tumble live ammo......I just looked at him and said "why would you want to"? First if the brass is just a little dirty it's just fine, if it's badly corroded it needs to be either tossed or pulled and reloaded. He keep pressing the issue and asked if it were dangerous, I gave him the best common sense answer I could. If your asking will it detonate in the tumbler.....I don't think it would, my concern would be that as the powder shakes around in the cartridge it would brake down thus changing the density of the powder and might create a bad end result. What are your guys thoughts on this.
