Can anybody tell me how many different grain bullets Frankford Arsenal used when they manufactured 30-40 Krag cartridges for the U.S. military?
There are many different bullet types and weights, including the “standard” 220 grain version, the Krnka-Hebler series, and lots of others. See HWS Vol. I Revised, Chapter7, pp 68 - 95. All will be revealed there.
