What is the F # of the Govt. loaded 45 caliber cartridge? Thanks, Hank

DWS I was curiious because most information that I read  about the old cartridges mention just loaded with powder and not grainulations by F#, thanks, Hank

today we only have a very few MFG who are making true black powder and we do have modern QC standards (let alone OSHA and State-OSHA standards)  so today's powder is much more uniform

in the 17th-19th century there were many more small mfgs and standards and QC was at best dubious, even within a given factory.  by the 19th century the production was becoming more industrialized and quality BP became more reliable.  ( the Civil War must have given a HUGE boost to the BP industry along with the mining, canal, and railroad building of the expansionist era.  I have never run across a good history of the industry other than  the Peters and King book)

BY the time of the 45-70 gvmt and industry probably had huge quantities of CW excess musket powder which was used in the gvmt ammo production.  After all development of the 45 and 50-70  TDs was an offshoot of efforts to reuse the CW surplus arms and equipment as a cost saver.

  I suspect that much of our knowledge of original 45/50-70 ammo comes from pulling old ammo and comparing the powder granuals to lat 19th cent and determining the F-FFFF grade by comparison.  the military probably specced it as "musket powder"
