Check these guys out... Good prices and they have different bullets for different uses.
Missouri Bullet Company
I have used their "soft" 158 gr LSWC for .38 special and Trail Boss for light loads with no leading. I have used their .357 "action" bullets in 158 gr LSWC .358 at magnum loads with also no leading.
I hope to one day cast my own, until then, Missouri Bullet Co gets my money.
