I have a quantity of lead ingots that range from BHN of 5 to 13 according to the tester I bought from Buffalo Arms. It is made by ST Machining, LLC.
I am going to make batches of 10 pounds and add linotype nuggets to raise the BHN to around 16 - 18 for .44 mag, .41 mag and .357 max. If my mix prior to adding known linotype is a BHN of 10, how many pounds of linotype will it take to get the hardness to 16. I have no clue what my ingots are except for some old lead pipes that came from an old house. They are soft lead just over BHN of 5. Do I add .3% of linotype per lb., to the mix that is around BHN 10.
