Up here, WW and/or Lead is going for $4-5/lb = 50# = $200
Tin... $25/lb = $25
out of date propane tank = free at the dump
Propane $25/20# = $25
Turkey fryer $40-50... no one gives them away. but no one uses them = $40
$200+$25+$0+$25+$40=$290/2800=$0.10357, round up to $0.104/boolit
you can buy bullets with free shipping for around that... but where's the fun in that?
