I have only recently delved into hardening cast with heat treating, my first batch were some I had cast 4 months ago. Heated in a little oven 1 hour at 425, and quenched in water. My only method to test the relative hardness is to put 2 base to base in a vice and measure the difference in length after putting the squeeze to them. I checked them every day and as expected the HT'ed one got progressively harder each day I didn't test after 7 days, the HT'ed version was substantively harder at this point.
A couple of days ago I cast some other bullet and water dropped them. Using the same method to test I was surprised to find the WD'ed appeared harder than the AC'ed after only 1 day, whereas the heat treated batch I mentioned before were softer than the AC'ed for the first couple of days. I think the alloy was the same, although I could be wrong about that. I know it's WW, but could be a different batch of WW's
