[QUOTE="4ked Horn, post: 61714, member: 11"] [ QUOTE ] The problem with this thinking is that there is a vertical component of the velocity that is retarded by gravity AND drag so with less drag it may go slightly higher [/ QUOTE ] I stand corrected. Upon further consideration I agree that there is an upward inertia that is affected by the density of the air as the bullet lifts above the line of sight. A resistance from the atmosphere above the bullet. Thinner air means that gravity is increasingly responsible for pulling the bullet back down. I still maintain my first writing is correct when the bullet is fired from a bore that is parallel to the line of sight (not that this would ever happen in the real world.) That is, a trajectory not intended to rise tward the line of sight. I also maintain that the distance at which the bullet would now drop through the line of sight (the zero distance) would increase by yards and agree with you that the increase in rise would be teency weency.
