Plug "herter's" into ebay and look at what comes up. There are still fans. They sell the old catalogues. Just that price tag is collectable. Many hint that Herter's was selling some other brand "2nds"... oh well. OR with great lube, Imperial, lanolin, etc., you could shove them thru a .308 die (or .309 or
) and have standard ".30" cals... No big deal. Me? For that many, I would hit the collectors... Someone will probably double your money for you... $2.78 x 2 = $ 5 56, MAYBE MORE... ha, ha... enjoy, happy trails.
