Help, I'm in the middle of processing 1000 Lapua .308 cases and need some advice.
Doing them in groups of 250, first 2 groups no problem, third group have come out of the rotary tumbler almost rose gold colour.
Normally I use a squirt of washing up liquid and a half teaspoon of citric acid to prevent water marking.
Unfortunately today I picked up Stardrops instead of Fairy liquid, no idea if I've compromised the cases.
Any help appreciated.
