[QUOTE="Mountainsheep, post: 125203, member: 5875"] Dr. B, Your observation is somewhat correct, but incomplete. A bullet with a high BC has a more aerodynamic anterior and lateral surface. This shape minimizes the amount of atmospheric force that may be encountered from either the front or sides. As for explaining this to Sir Isaac, he did all of the research and experimentation necessary to prove his theories (at least until the time of Einstein) Actually, it took Newton some time to clarify the concept of force, which had previously been unclear. This is discussed at length in Never at Rest, by Richard Westfall To put it in his own words (although actually he wrote it in Latin, this is from an 1803 translation): “If a body impinge upon another, and by its force change the motion of the other, that body also” (because of the equality of the mutual pressure) “will undergo an equal change, in its own motion, towards the contrary part. The changes made by these actions are equal, not in the velocities but in the motions of bodies; that is to say, if the bodies are not hindered by any other impediments. For, because the motions are equally changed, the changes of the velocities made towards contrary parts are reciprocally proportional to the bodies. This law takes place also in attractions.” This should clarify some of the confusion by illustrating that the lateral velocity of movement is lower in a high BC bullet, resulting in lesser distance in wind drift; as proven by your point (D= T x Vw). I hope I haven’t been offensive or derogatory toward you in any personal manner. I enjoy these controversial topics and the friendly debates that ensue from them. Your points are very astute and give me a challenge to ponder; therefore I learn a little bit more about ballistics and LR hunting from this. All of the intricate details involved in LR accuracy continues to increase my appreciation for your talent. Dave [/QUOTE]
