The Civil war changed that as rifled muzzle loaders extended the kill zone to 200 yards and beyond and those square formations were suicide squads. But that returns me to my question. Give every soldier, or just 1 out of 8 a lever action? Well, that would have changed the game a whole lot quicker. I'd have taken a Mauser over a Winchester for most applications if it were me. But the Mauser's weren't there when the choices were made. it was levers or single shots. What jackass would want a single shot?

Rifled muzzle loaders have been around for some time. There were Rev. War squads of marksmen tasked with killing the British officers, which PO'd said officers quite a lot, it's just not done and it's not at all sporting don't you know?
The squares were not suicide squads, they were a defense against the cavalry as there was no flank to for the cavalry to attack. The older square formations with pikes were referred to as scilltrons. And with the long rifles with long steel bayonet on the end were an effective tool against the horses themselves, as the horses could not be goaded by their riders to run into a wall of men and steel. It was only with the advent of cannon that squares lost their value, as did massed formations of any kind - a lesson not learned until after WWI.
At the ranges cavalry fought on the Western Plains, the single shot was a rifle, the lever action mostly a glorified pistol shooting a pistol cartridge. They were roughly equivalent to going into combat today with a 9mm Hi-Point. So if you are shooting at 2-400 yards, the lever action is not such a great tool as even if you could get the .44-40 bullet that far, it wouldn't do a whole lot of damage when it eventually arrived!
True rifle rounds did not appear in the lever action for some decades after the lever action was perfected. One of the first successful and generally available lever action was the Sharps carbine in the 1860's. The Henry Yellow Boy was introduced
after the Civil War was over. The early Winchesters - the 1873, 1876, etc. were all small cartridge rifles. IIRC, it was not until the Winchester 1892 that you were able to get a true rifle cartridge in a lever action. In a carbine, you still had range and accuracy at range issues, and in the 1890's there were bolt actions with box magazines - and excellent accuracy - that made the lever action obsolete.
Where the lever action excelled was rate of fire at closer ranges, as demonstrated at the Wagon Box Fight. And that was won dismounted from behind barricades - the wagons - by the civilians, not the military with the Springfields.
