I have yet to cast a bullet, but plan to start this weekend. I have two sets of 6-cav 45acp molds that I bought used from a castboolit member, and they are pretty dirty.
Should I clean off all of the black, sooty stuff? In a few sections I have scrubbed off and found the shiny aluminum behind. The black stuff kinda 'flakes' off in pieces when I scrub with water/toothbrush.
Thanks!
