The best deal is to order the around 60lbs lead ingot from roto metals $109 since it is over $ 99 you get the free priority shipping , other wise from roto metals you will pay about double that price or more for the smaller stuff or mixed ... I need to order 2 more - I am down to a half ingot left ... good to have some in reserve https://www.rotometals.com/whole-lead-pig-ingot-57-62-pounds-99-9/
Dan it says no free shipping in red letters for the whole ingot, the split pig ingot has always been free freight and that's what I'd order if I did. I just started on my second half of the split pig ingot myself. I'll probably wait this I have a quarter ingot left before I order probably. The split pig ingots last me a very long time.
Dan measure the diameter of the 359 slug because the 356 slugs I cast were only .354 probably due to the fact both probably call for wheelweight lead and aren't as large in diameter as what they're supposed to be, heck if you're getting those kind of results I might not even bother trying to size them, just use them like they drop when I get the mold.
