[QUOTE="GeorgeS, post: 1517165, member: 107925"] I guess that your 8th or 9th grade physics teacher didn't do you any favors, because the acceleration due to gravity is not "16 feet per second per second" but rather 32 feet per second per second. That IS rocket science, as well as simple physics, since rockets have to contend with the reality of gravitational constants. Moreover, while the trajectory of a stick launched at X degrees but with a non-coaxial attitude is deflected in response to air pressure in a relatively predictable way, that is decidedly not the case for a bullet spinning rapidly owing to the response of an object experiencing gyroscopic force in addition to wind pressure and gravity, as can be readily ascertained - from an 8th or 9th grade physics experiment - and an additional force is imposed at right angles to the externally-imposed force. You may choose to look this up. As an example, if a bullet is spinning clockwise along its axis of travel, and is subject to a crosswind from right to left (wherein the center of pressure of the bullet is ahead of the center of mass, which is almost always the case), the force tending to deflect the bullet path and particularly the bullet yaw, to the left, will also, owing to the bullet's spin angular momentum, cause the nose of the bullet to point upward. The bullet will thus rise, and strike the target both to the left of the aim point and above the point at which it would have hit had there been no wind. Given the flaws in your argument, I would not inveigh against others simply attempting to ask a question as if they were fools of the first order, when it is clear that your abusive and incorrect answer clearly identifies the fool in this debate.
