Thanks for advise and help folks. I posted earlier that I found some unidentified content wire solder from long ago in my shop today and sacrificed it to making bullets tonight. It was the only source of tin I had. Period. Guessing it was 50/50, I used basic math to make an educated guess at the 2-3 percent proportion needed by weight. I calculated that I had enough to cast 7 alloyed pounds of 125 grain, .358 Lee RNFP. I just today learned that a kind gentleman here is going to help me by providing some alloy metals since I have yet to find any locally. Wonderful man, and I have agreed to pass on the kind gesture to another casting enthusiast in need when an opportunity arises.
My gear is the simplest and most affordable to me. The pictures below show my setup. The sheet of chipboard on the patio table prevents drips from falling through to the concrete where any of our four indoor/outdoor dogs could eat it. The ingot molds are made up or bought as I learned from reading old threads here. I tried my first casting last night and had wrinkles which the solder fixed (thanks again for the help). A stainless container filled with water and an old cloth caught the hot bullets right from the mold. My mallet is scrap oak sanded to remove splinters. The container and mallet were ideas gleaned from old threads here too.
The last light was fading as I completed re-melting down all of last nights slugs, of which 20 percent or so had wrinkles. I want to do it as right as I can until I have more choice in lead alloys, and the solder today made a world of difference. It was expensive and now is gone but I did the right thing and am glad of it.
I move on now to another new process to me. Sizing and lubing. I bought a Lee .358 sizing die I will use in my new Classic Cast turret press, right here at the kitchen table. I'll do my research here tonight via old threads and maybe posting a question to address anything I'm unclear on. One concern I have right now is damaging the fresh, un-aged 98% lead/2% tin slugs when tumble lubing them with the only lube I have, Lee Liquid Alox that came with the sizing die. I may find I need to roll the slugs on a saturated pad. Tomorrow, after a cardiac physician appointment for my loving spouse Penny I'll begin the new processes. That is, unless I find I need to age the fresh bullets a period of time before sizing them.
I really welcome critiques here. It is a little daunting to learn casting from reading books and archived threads. I can't imagine how Daddy and I could have done it back in the 1960's when I was a child and we had plans to cast for his .32 ACP Walther. He had no friends or any interactive methods to learn the art. Just books. Don.
