[QUOTE="Michael Eichele, post: 474808, member: 1007"] Michael: Once this is figured out, the rifle is taken to 750 yards. Just before it is fired at 750, a dead on 300 yard zero is verified. Then 750. In every case, when using this method bullets have fallen into the middle of the X ring at 750 yards. JonA Drop at 750 from a 300 yds zero is absolutely and completely meaningless as a method of verifying BC's. [B]Like hell it is meaningless. Use what ever method you like to determine a BC. The proof of accuracy is where the bullet hits the target. Now if you are talking getting on paper at 1500 yards then I could concede and say you are right, it is meaningless. For 700-800 yards, it is anything but meaningless.[/B] Michael: The point is that my methods, Bryans methods, and every body elses methods are going to be different and in different circumstances. There is no way we are all going to match. JonA: But they should, if we're all doing it right. Unless there's something wrong with a rifle/bullet combination used by one of the people measuring, if they all do it right they should all get the same answer (within a certain amount of variability). [B]No they should not match. If I use a 308 win to test a 210 VLD with a 24" 10 twist barrel using top velocity capabilities and you test the same bullet from a 30-378 11x 30" barrel using top velocity capabilities, the difference is going to be QUITE noticable. The only time they should be close is if different shooters are using similar velocities, similar stabilty factors, and similar bore qualities.
