[QUOTE="MikeC, post: 280912, member: 1604"] Remember the Law of Gravity? Everything falls at the same speed. :P 32 ft. per sec. squared The reason a small bullet might not be as effective as a larger one at extreme distances is because of the lack of momentum in which 'Wind Drag" effects the smaller, lighter one slowing it faster. Bullet drop is an element of time only. The longer it takes for it to get to the point of impact, the more it will drop. No matter the size. "Ballistic coefficient" is the measure of how a bullet slows in regard to wind drag. A longer more slender bullet with the proper ogive will tend to maintain it's velocity better. There is no one caliber that is best for all situations. That is why the military uses the BMG 50 Cal and the .223 also. "P. O. Ackley" is the man to read about using different velocities at different game and the effects thereof. In his second book, they shot well over a thousand pigs and goats to assess the killing properties of different bullets and velocities. "Hydraulic Shock" was found to be very effective. Personally I have the "NEED FOR SPEED" . :lol: The lighter bullet being affected by "Wind Drag", yes. On being blown off trajectory no. A side wind will affect both the lighter bullet and the heavier bullet the same. [/QUOTE]
