Have about 50 pounds of lead, wheel weights, and boat ballast from keels. Put a lot of it into Lyman ingot forms.
I am ready to start casting since I have all the tools. Plan to use coating and not lube.
The question to me remains is hardness really important, somewhat important or not at all.
I will use these rounds for training and plinking. I am not concerned with putting 10 rounds into the same hole. Or any accuracy even close to that.
Just want to be safe, make a round that goes boom and stay safe throughout the process.
