So I cast some nice 200grn 309 boolits in my nice new NOE mold. The melt was 17lbs pure PB, 1.5 lbs Royo super hard, and .5lbs SN. Well I got the mold to hot and my melt was too hot and they were all very frosty lol. Well I water dropped them and they were so hard they climbed together like they were steel.i figured if I threw them into the toaster convection over and then water deopped them I could soften them up and get them to a more uniform hardness. Well I decided to drop them in ice water to make them very hard and surprising about half of them shattered lol. Anyone ever experienced this?
