[QUOTE="Trickymissfit, post: 803693, member: 25383"] just thinking, and have not ever given thought to prove or disprove the thought. The Earth's gravity is one of the few true constants we can work with. Everyone knows that a projectile travels in an arc. In doing so we are somewhat overcomming gravitational pull (the one constant). A major factor to this is the rotational speed speed of the mass in travel. Now it would appear to me that with the barrel (in this case) set dead parallel to the Earth's surface, the peak of the arc should be the highest rate of spin on the bullet. As it drops off (going back down) the rate of spin should be decreasing. Thus relating to loss of veocity. Back to the Army. They use an Ohler 43 (nothing like the 35P) and another super sophisticated rig to figure the B/C of their rounds (including tank ammo and small arms). If I remember right they us more than one in tandum. what do you think? gary [/QUOTE]
