if your going to be buying a lee mold for your 357 you can use that mold to slug the 9mm also. just waite to buy your sizing dies and the 9mm mold till you slug both barrels. thats what i would do. or pm me your address and I'll cast up some soft lead 358 bullets for you to slug them with either way. if your buying lee molds its probably gonna be a .358 mold and a .356 mold. not much choice with lee's. just lap them out if they arent big enough.
