Hello
In fact, the repeating rifles had poor range and the Indians quickly began to use arrows and bows to protect themselves.
But as it’s shown on http://www.custerwest.org , the Indian casualties are today estimated as high as 200-250. The battle was hard, 210 men were fighting with Custer to the death, and 400 were out of the battle with Benteen and Reno.
the Spencer did have an accuracy and distance advantage over the winchester of about 3/1 but the winchester held 15 rounds.
thee Spencer’s also jammed with the copper ammunition.
the biggest factor was Custer, Disobeyed his orders to basically a re con mission, not engage the enemy.
FYI one of grants chief complaints about him was that he had more horsees shot from under him & more men killed than any one else in the civil war.
Custer’s best press agent after his death was his wife, Libby,with out her much less myth and more fact would be availible.
