It was my understanding that a maxi ball is like a regular bullet- flat bottom, conical shape.
I grasp the idea of a minie ball; undersized, the skirt opens up on firing.
But how does a maxi ball work? If I'm wrong and it has a hollow base, great. If I'm right, it would seem to either be greatly undersized and ergo just rattle down the bore, or so oversized you'd need a hammer and long ram to get it down the barrel. More so than a wooden ramrod, given the large bearing surface vs. a round ball.
What gives, what am I missing?
