OS OK,
I have a "list" of Alloy ingots inside of every Reloading Manual I have. And a good half dozen Laminated copies in Various places with my Casting gear and molds.
OHAUS - Linotype
LYMAN - #2
SAECO - 20/1
RCBS - COWW
LEE 1lb - Pure LEAD
LEE 1/2lb - Monotype or Tin. Mono is painted Red.
Blank(RCBS) - Unknown / Testing Alloys
Lodge Scones - Range Scrap
I also have a few dozen square ingots that measure 2"x2"x1" of COWW's that I bought from a Fantastic Guy here on CAST Boolits.
I just weigh them like my own various ingots and write the weight on each one so I can Blend each alloy perfectly.
