If this works, it solves two problems. The high price of bullets for 50 bmg and the ban at most range of using bullets with a steel core. A friend made me an adjustable mold that casts a .503 dia bullet using #2 alloy or harder. My first batch is set at about 750 grs. Paper patches are 3.140" long and 1.5" wide. I dropped the bullets in a jug of water right out of the mold and they are 20 bnh or better. If anybody is curious I will keep posting how this works out.
