[QUOTE="Broz, post: 667200, member: 7503"] LTLR I disagree, this why I posted about the inaccuracies out here. Have you ever left your computer program out of this and done some actual wind drift testing? I have. It is not easy and requires several rounds fired so as to eliminate the fact the wind could be varying. But here is what I do. Two targets located at the same distance in an area that has flat terrain so a more constant wind is possible. Then with a helper watching the kestrel fire the lighter bullet with the higher MV. Next shot I alternate to the other target with a heavier bullet and a slower MV. I try to fire with the same wind at the rifle. Note that at impact the programs will usually say the heavier bullet is now faster. But this is not about speed. It is indeed all about drift. I only test with the dial up method for elevation as I feel I get a better / finer point of aim with using center crosshairs. I feel hold over leaves room for error. I use no windage correction. I am only interested in seeing actual drift. I have tested bullets with almost the same rated BC's however as in most cases the heavier bullet will indeed have a slghtly higher BC. I can not think of one time where the heavier bullet didnt have less drift than the little bullet with a faster MV. I have paid the dues and done this alot. You can take it, leave it, or do it for yourself to see. I have done it enough times that my confidene is good about this test being accurate. This is why I thought this article was good and had something to offer readers. Not only one but two highly respected shooters (one a maker of high end barrels) have come up with the same results as I did. Thats good enough for me. 3 out of 3 ain't bad. Elevation for a shot is a controlled correction we can master. Wind drift is another story. It is by far more important for hunting than many other things as far as shot placement. This is why I do the testing before I settle on a bullet. Jeff [/QUOTE]
