Bullet flight question

[7br]

Does the axis of the bullet stay parallel to the axis of the bore or does it stay parallel to the bullet path? IE, if you shot a bullet flat from a bench, would it hit the ground nose first or would come in like an airplane landing? Doesn't really matter, but I got to thinking about it last night?

At some point the bullet would become unstable as vel is lost. So it would depend on how much drop along its flight path. Off a bench, I would expect it to dig in nose first, like a plane crashing on decent.

IIRC, pressure causes the bullet to fly pitched upwards, slightly nose high. If this is the case AND you fired parallel to, say, the surface of the Bonneville Salt Flats, I believe the bullet would land in the same manner as an airplane. In a perfect scenario.

Sandy Hook Trials in 1879 resolved that question. Bullets launched at 40*, impacting at roughly 60* nose first

Simple question but the answer is fraught with complications. Sandy Hook provided insight to a specific bullet, twist rate and muzzle velocity, nothing more or less. Don’t be too quick with conclusions on this topic.

Yes, if 'overstabilized' the bullet will fly 'nose up'.

They all fly nose up to some degree. Gyroscopic Stability Factor (Sg) is the fly in the ointment. They all yaw left or right depending on direction of rotation. Sg has influence here as well.
