Default RE: How important is the break in procedure?
I don't know where you got your temperature of 300 degrees. Brass keeps its hardness to about 500 degrees and must be above 600 degrees to anneal. 300 degrees is when the grain crystalizes, the recovery temp is the higher temp the metal must reach before annealing can begin.
