[QUOTE="JakeC, post: 2581994, member: 115819"] He's literally just asking you a question in a thoughtful conversation and you pivot straight to "is this a test?" it sounded like a legit question to me. Hardness and bearing surface would effect pressure on rifling more than density, but what you were saying indirectly is that without mitigating techniques like grooves a lower density material of the same weight will have more surface area. That took me a second. And as far as parabolic drag, I thought "all drag is a parabolic function so we just say drag". Parabola refers to the shape of a drag graph, the flight of a projectile, and the shape of hammer drive bands. I wondered if you were referring to a different problem or a subset of drag types or a new BC function. Is parabolig drag just a qualifying descriptor, like saying exponential growth? Or does it refer to something specific? [/QUOTE]
