1866 and 1873 Winchesters were available but genius army brass were leery of ammunition consumption.

The Union Army did purchase large numbers of Spencer rifles & carbines during the American Civil War, but sold them off a rapidly as possible after 1865.
Orthodox military thinking of the day favored long range rifle fire, and the Spencer’s rimfire rounds were incapable of firing a suitably heavy bullet to the required range. The Henry rifle’s cartridges were even weaker.
No gunmaker succeeded in developing a repeater that could handle the 45-70 cartridge and pass all the grueling tests the military establishment required. Additionally, repeaters were much heavier than the single-shot rifles. Try hefting a Hotchkiss, a Keene, or a Winchester 1886 and see for yourself.
No European power of the time except Imperial Germany fielded a repeater, and the Germas (Prussians) chambered theirs (Mauser 71/84) for the much lighter 11.15x63Rmm cartridge.
