Ok This might go down as stupid question of the week but....
With what is going on outside I have decided to start casting my own "boolits." I have been collecting lead for 10 years for this eventuality. I have the lyman pot, book and dipper. I want to cast 9mm (maybe rifle later) and I have not decided whether to lube or tumble yet. I am a reloader.
The lead I have came from three sources, wheel weights from my buddy's car repair shop, boat ballast (lots), range lead ( small amounts,) and fishing weights. I see where the BHN number seems important but I do not want to go to the trouble of buying a tool to determine the BHN. Now I will mostly plink this, so accuracy and precision are not a priority, just a round that SAFELY goes boom. If this step proves to be too complicated or expensive I will probably not proceed.
So can I just cast any and all of it without regard for the 5 to 20 number?
Sorry for the so basic question.
