I deprimed for the first time this week - about 240 pieces of 9 mm brass. Today, I loaded up a Franklin Arsenal rotary tumbler with the dirty brass, new S/S pins, water, about 3 cases full of 2X Dawn and 1 1/2 cases full of Lemi Shine. After 3 hours ( 2 1/2 plus 1/2 hr with fresh rinse water) everything came out clean and no pins were lost. However, the cases were "bronze colored" not brass.
Here is the end product with one uncleared case as a comparison:
Is this because of too much Lemi Shine with the acid etching or reacting with the zinc? Or is this likely due to conditions with my local water source? If Lemi Shine, what amount do you use to get shiny brass instead of bronze colored cases?
Also, am I correct in assuming that this is merely a cosmetic issue?
Thanks
