Just for clarification, I didn’t give the ordinance bureau a second thought. My focus is on what the synergy of what Spencer, Wilder & Rosecrans created. The ending the war thing is a straw man intended to tar me with something I never proposed.The speed of sound in fps (feet per second for those unfamiliar) is approx 1125 fps, the 56-56 Spencer round has a muzzle velocity of approx 1200 fps, so it is supersonic, though just barely, at the muzzle. How much this affects accuracy when the bullet quickly becomes subsonic, I have no idea. And yes, I have fired plenty of muzzle loaders, presently I own an PH P53 Enfield, a mutt of an 1858 Enfield two bander that Lodgewood did up as a Confederate import, and a 1803 Harpers Ferry rifle.
Yes, they were innovative and yes they were tactically important, in a very limited way, on engagements where they were used, however; the technology was in its infancy, the infrastructure was not yet there to manufacture them or the ammo in the large quantities required to have a real bearing on the outcome of the war, nor were the logistics of the time able to deal with the ammo requirements if it had been possible to arm large units of men with them.
Maybe I extrapolated too much from your earlier posts regarding the repeaters and their influence, It seemed like you were headed where you have been before, intimating that had the ordnance dept not resisted them, the war could have been shortened by years.
