A portion of an estate contained ~200#'s in 2# rectangular truncated pyramid ingots of a composition-unknown lead-alloy impressed as "LYMAN" (so I know the mold) and it has been a question trying to decide what alloy it may be. There were no notes from the caster. I suspect it to be Lyman #2 (90/5/5 percent Pb/Sn/Sb lead-tin-antimony, 15 BHN). I have not, as yet, pencil tested for hardness.
Clues include the alloy belonged to a competition 30-06 Springfield Garand shooter, the FFL for his group. He cast for his Garand. The boolit mold(s) remain unknown although there are a few remaining rounds which could be pulled and the boolit shape investigated. He bought powder, primers, and components in bulk quantities and distributed proportioned quantities among his group's members, a very good way to spread the cost of HAZMAT and shipping.
It will be mostly never before I may need any of the estate alloy as I already had a lifetime supply prior to discovering and loading that portion of the estate. Short of paying for a metals test, are there further recommendations for discovery?
