I have started to consider casting my own after many years of reloading store-bought bullets (jacketed, hard cast, and plated). Lyman and Lee manuals have been perused and the major question is sizing cast bullets. By the way, I am leaning towards Lee casting equipment.

According to Lee, their molds are precise enough that sizing is not required most of the time. Seems that slugging a barrel will positively determine if sizing is required or not. However, store-bought bullets come in one-size-fits-all dimensions. So is sizing home-made bullets necessary? Should mold diameter be the same as the diameter of a same caliber jacketed bullet?

I would appreciate TFL members with Lee mold experience to advise on the necessity of sizing. Thanks.
