Going back the OP about cost I'd suggest a lead bullet you cast yourself. It's what made me decide to cast my own.
I was shooting Kaido's FN bullets through my Ruger Old Army, but at the then $40/100 (now $50/100) + shipping expense I felt it was time to do it myself. I bought simple and inexpensive Lee equipment and molds, along with a custom mold from Accurate Molds for WFN bullets to shoot through my percussion pistols. I bought lead from a scrap yard for $1/pound. Outside of the equipment cost that gives me thirty-five 195 grn bulets for a dollar. Can't beat that price, and in no time my equipment costs were paid for.
