Self-loading .45s chunking 500-plus grains a pop go through an especially obscene amount of bullet metal. Fortunately I am able to recycle my own and have enough to "stock the cycle" well thanks to years of diligent scrounging, dealing, and a few very generous people along the way. Wheel weights are virtually unobtainium in these parts anymore, so finding a shop that will part with them is a blessing indeed. Take care of those guys well! Auto techs are a perpetually hungry lot and enjoy BBQ sandwiches, meat-heavy pizza, extra-large cookies, and beer money. Just sayin'.
