Re: Balistc Coefficiant
Unfortunately barts right. Theres no quick and dirty method that will do it. If you are talking about 2 bullets launched from the same cartridge, generally, if both bullets are of equal design, and the BC commensurates with the weight increase, the heavier bullet will always have less drift, and the lighter will have a flatter trajectory. It won't usually be a radical differance, but thats the way it usually shakes out. Occasionally, like in the case of the 308WIN, the heaviest bullets can't gain enough speed in normal length barrels to make up for the increase in weight. Also, the heavier bullet will eventually win out in the drop area as well over the light one if you look at a long enough range... but even then not by much, and were talking 1500yds and better. I shoot 220SMKs out of my 300WM, and im liking 180Bergers from my 7mm esty dubbaya, so to me, the better wind drift of the heavier bullets is worth the small increase in max height at shorter ranges... but part of it is a personal choice. If youve got a cartridge and bullets in mind, I could give you some specific numbers.
