I'm intrigued. I think tomorrow I will visit local shops and see if I can accumulate some wheel weights, and for how much. Like I said, right now, I am at <7cents a piece for hard-cast 158gr SWC's, and the supplier now has soft-cast for around 5 cents a piece for 158gr SWC's, and even less for 148gr DEWC's. Shooting target 38's does not require hard-cast as they are well under 1k fps loadings.
I am still not sure if this route would be beneficial to me as the cost to accumulate all the gear to cast would not be recouped for several yrs at the rate i shoot. Thanx for the link, I will bookmark for further reference.
