Smelted up my first batch of pewter today. I've been smelting a lot of scrap lead lately, casting ingots. Today is the first time I've ever melted pewter. Amazed at how fast it melts compared to lead. Guess it's the lower melting point. After fluxing the melt with sawdust I hand ladled the clean melted material into my Lee 200 grain bullet mold, casting 200 grain pewter/tin bullets to add to my casting pot as needed. Inspecting these bullets I was surprised how light the bullets were compared to lead, certainly not 200 grain in weight as they would be if cast from lead. This prompted me to wonder. One standard alloy recipe I see is 49/49/2 meaning 49% COWW, 49% pure lead, 2% tin. My question is what are these percentages related to? I assumed weight, but after looking at those light weight tin bullets, would the percentage be volume? Which is it, by weight or by volume? I'd estimated using one bullet to 15 lbs of alloy, now I'm thinking that is way too little.
