A few weeks ago I picked up a bucket of WW from a local tire shop. Although I didn't weigh the bucket when I picked it up they claimed it held approximately 150 lbs of weights and happily took my $60 in return for me carting it off. After spending four hours sorting out the zincs and steels as well as keeping the tape weights separate (for casting round balls) I fired up my brandy new Lyman Big Dipper and set about casting ingots in anticipation of someday receiving my molds from MidwayUSA.
Many hours later I'm left with 93 lbs of hard lead and 9 lbs of soft for RB's which brings the price to roughly .60 per lb. Given the fact that I've got at least 12 hours total invested in the ingots I can say that "I'm not impressed" with the overall cost of using wheel weights. But on the other hand it has been a great learning experience. Now if the Brown Truck would please deliver my molds I'll someday actually get to cast some boolits and quit having to sacrifice a valuable body part just to lay my hands on some .452's to feed my 1911's.
I realize that a lot of you use WW's for casting but for me I'm afraid that it just doesn't make sense either financially or time wise. After I go through the 100 or so pounds of lead that I've got stacked on my shop floor I'd like to just buy ingots either off eBay or from some other supplier. So far I've found several places/people that sell for around $1 per pound.
