Does anyone know if wheel weights contain too much tin to be used as properly expanding cast bullets? This thought just came to me, as I was thinking of a deer I killed two years ago with some bullets I cast with wheel weight lead. I shot him quartering to, and hit him good in the shoulder, but had to shoot him again as he would keep getting up, not looking like death, but just hurt. I was wondering if the bullets I cast had maybe exploded even. Thoughts or any experience maybe?
