[QUOTE="danacobb, post: 35203, member: 1696"] I also tried running the numbers with a BC of 1.25 and thats still to low. I also tried running the numbers shooting at an angle. They came out closer with a 30-35 degree shooting angle, but only work from 300-600 or from 600-800 and there still not right on. Something's got to be wrong???? Just ran the numbers again with a MV of 3350 and the numbers come out much closer. Also tried the match the trajectory using your come ups, and exbal calculates an MV of 3401 with using a BC of .512 but the 800 yd comes up shy at 13.5 I'm just learning all the tools of this Exbal software, (got it last week). I'd have to say thats its a pretty good program. Probly didn't help, but I tried [img]images/icons/smile.gif[/img] Good shootin [ 08-16-2004: Message edited by: Cobber ] [/QUOTE]
