Best method for sorting I came up with was to dust the shot with a little graphite and then I had about five stainless steel 4-5 quart bowls that I drilled four of with different sized drills using a shot size guide to get roughly in the ballpark of drill size. So you start with a stack of bowls and dump about a cup of shot in, then pick the top bowl up and start spinning and shaking it over the next size down bowl, you repeat until you get to the bottom bowl which has no holes in it.
Normally I would remelt the top bowl and bottom bowl. The top had pretty large holes, basically anything smaller than #4 shot fell through and anything bigger was just crap anyway. It basically took two sifting bowls to get to stuff that was sort of round.. I had an idea of using a pane of glass on an angle with compartmented collector on the bottom, that would roll the shot to sort the mostly round ones.. I never built that because I hit a yard sale and bought like 14 bags of lead shot for like $10 each.. So I was kinda set for shot.
One other thing. If you are trying to use anti freeze to drop the shot, it has to be straight anti freeze not 50/50.. Straight antifreeze is basically soluble oil plus some nasty stuff.
If fabric softener works I'd stick with that, antifreeze REEKS when it catches on fire... And yes it likes to catch on fire when you're using it straight, lovely purple/green smoke that smells somewhat worse than a tire fire.
The old hot shot towers had to be something like 100 feet tall. Now they use forced cold air and like a 20 foot tower into coolant.
