I've read a number of posts which talk about picking up a few pieces of range brass to get your annealer calibrated with the tempilac, so you do not have to waste any of your good brass. I just finished annealing my first batch of brass and applied tempilac to 2 pieces. They look completely usable to me, but wondering if the residue might have any unintended consequences when mixed with powder? Hoping someone with experience can educate me.
