I was just wondering. What affect does the shape of the bullet have on the way the bullet behaves while in the barrel. Apart from going out the other end, how does their shape affect their performance. Specifically does the typical FMJ boat tail round expand less in the barrel than the old style flat based bullets. Some bullets are fully covered by the jacket including the bottom, others are not. Any thoughts on the matter. I realize that a lot of the design difference has to do with the areodynamics and what happens when it impacts. How much has to do with what happens up front.
