[QUOTE="M67, post: 699471, member: 26259"] ajhardle, Gravity is the reason that a bullet drops more when shooting uphill than downhill. I can throw a rock farther downhill than uphill right? This is generally not seen when shooting, hardly even in archery, since the kinetic energy of a bullet is far, far greater than the potential energy change due to the bullet travelling up or down - unless at silly distances and steep inclines... [I]My question was concerning the fact that Bulletflight predicted a much bigger difference between look-up and look-down shots than Shooter[/I]. As one solution had to be (more) wrong i wondered which, and why. I suspected, and Brian and Robert Silvers, (and Jonathan Zdziarski) confirmed that the difference is due to Shooter correcting for the changing air density (and thus changing drag) along the trajectory. I can only assume this correction is based on the ICAO std. atmosphere and it cannot be valid under all circumstances, but still is far better tha doing no correction at all. Thus the result Shooter presents is very close to what actual firing will, and in fact does, confirm. K [/QUOTE]
