Scoutscope,
I buy all of my lead wire from Corbin direct. It's not worth casting your own, or trying to find a better or cheaper source. Corbins lead is 100%, no alloys are introduced, so the wire you buy now, is the same as it was 8 years ago. When other alloys are introduced to the swaging process, there is a danger of too hard of lead due to alloys introduced. Lead wheel weight lead will damage the dies, and possibly damage YOU!!!
I get all of my wire from Corbin, .170 in diameter, in 10 pound spools. 10 pounds of lead is approximately 70,000 grains. One spool is $50, if you buy a case of 4, it costs $180. The shipping is up there, but not to the point it is cost prohibitive. I still have about 100 pounds left, I'll buy 3 cases at a time in the future.
I'll make another swaging video that is a little more detailed than the last one, due to my award winning camera work. One thing I will show in more detail, is the cheapo adjustable cutter that I made, that works like a charm. Anyone reading this, if you are inclined to get all or some of this equipment, leave out the wire cutter. It works well, but for lighter pellets that we use in the airgun community, it's a hindrance. It is really designed for making longer cores to be jacketed for powderburners
