Yondering, I understand the shortcomings of that very simplified test. But, it does give an idea of the question in hand. Personally, I was not too interested in the process because I ultimately want to use my PC'ed bullets for hunting and want them soft enough to expand reliably. I'm still playing with developing a good alloy for that purpose. No water quenching for me! So far, the unquenched bullets have shot very well indeed.
