If Custer's men had still been armed with their 50/70 Sharps they would have done better at the Little Bighorn. But the army had them turned in for trapdoor carbines in 45/70 and inside primed Benet copper cased ammo that caused problems in battle.
I always go back to them being in the open on the side of a hill. With no cover and outnumbered it was just a matter of time anyways
