Keep in mind, Sharps rifles were also used for combat against wild native americans, too. They were pressed into service as sniper’s rifles when needed. Billy Dixon should and killed a mounted indian whom was hundreds of yards away, with his Sharps rifle. Some see these as nothing more than a hunting rifle, but during the time, they were used for defense as well.
...Billy Dixon's shot was 1538 yards if I remember correctly...
For the rest of his life, Billy Dixon never claimed that the shot was anything other than a lucky one; his memoirs do not devote even a full paragraph to "the shot"
Takes a pretty healthy fella to lug a Sharps around!
That's why they rode horses and mules. Don't forget the Remington rolling block rifles. They were also popular with the buffalo hunters.
Buffalo Bill Cody used a Springfield .50-70 rifle. It was called a "needle gun" due to the long firing pin.
