I did test Evapo-Rust and also used it on cartridges, shrapnel and bullets from an actual case from the former Yugoslavia. It worked very well. The end result was comparable to our old acid mixture but Evapo-Rust is much safer and easier to use. I cannot give you to much details on the case however. I hope you understand.
