Bought some 1/25 lead, have a Hoch .322-200gr no-taper mould for fixed ammo for .32-40 Highwall. Out of 200, I randomly selected, sized (.321), and lubed (SPG) 50 boolits to see how they would come out. Weighing the 50, the weight varied from a low of 197.4 to a high of 212.8 grains, averaging 208.224gr, std deviation 3.257gr. Is there something I should be going to narrow the minimum and maximum weight, or is this typical when moulding bullets?
