Do you have a hardness tester? What is the difference in hardness between the two ways [BHN speaking]?
I am going to have a heck of a time with hardness (I think) since the pedigree of the base alloy is unknown. After remelting the former ingots with the latter to generate greater consistency throughout, I hope I will end up with about 75% lead and 25% WW's. Then I want to check the water dropped boolets against air cooled at day 1, 3, 5, 7, 9, 11, etc., through day 49 (7 weeks) as others have done to see what, if any, change occurs with time.
My two boys [19 & 15] are "working me" so we can smelt lead together. They are as hooked as am I. So far we've "cooked up" about 66 ingots in the 2.5 to 3 pound range. What a interesting hobby and we have not started to cast boolets yet, or shoot any (still waiting on an exchange for the 110V [60 Hz] of the 240V EUR [50 Hz] RCBS Pro-Melt 22# furnace I received for Christmas), and the purchase of a few additional moulds (357 x 180 gr, 45 LC x 300gr., 30-30 x 170 gr.).
