I cast some 432-256 boolits yesterday. They sure are pretty and weigh 262 grs from my alloy. I sized and lubed 50 in a .430 die. I was afraid they were sized alittle small for my Redhawk. But I don't have a .431 die so loaded some up anyway. Over 18 grains of 2400 and a Federal Match primer they shot great. My best group was 1.3 inches at just over 25 yards. I'll take that anyday.
