Ok, so I have been casting bullets for awhile now. Just plain jane WW stuff and have gotten my technique down pretty good. I have a smelter, lee 10 lb pot, and a couple of Lee aluminum molds. I have never sweetened my lead because I didn't have any tin and besides, improvements without tin could be made. Now that I have gotten WW technique down to where I'm happy with it, its time to take my casting to a new level. My bullets function reasonably well but they are certainly nothing like some of the pictures I have seen on this forum. I bid on some solder the other day on eBay and won the bid. Now I need to modify my technique to incorporate the solder. I have several options, but let me list my supply first. I have about 50 lbs of smelted WW. I have about 150 lbs of smelted stick on weights. I have 3 lbs of lyno type. I have 8 lbs of 97/3 solid core solder. I could blend up some batches of various recipes from the "Definitive answer" page sticky in my smelting pot. Which by the way is just a 5gal propane bottle with the top cut off. Or I could melt the solder down and let it drip out of the 10 lb pot into water turning it into shot that I could sweeten my pot with as I go along. Most of my aim is to improve my pistol bullets, but I would like to also start experimenting with some rifle bullets that will require different blends. All that just to ask, how do you guys do it. Do you create reserves of various blends, or do you mix as you go? I'm sure everyone is doing it a little different, but there is probably some good ideas out there.
Next question. I cast between 600 and 650. When I hit 650 I add another ingot. Is this window going to change (I'm certain it will) and do I need to narrow this window for best results.
