[QUOTE="Jeff In TX, post: 35209, member: 1522"] Jerry, Sorry I'm not questioning your results only trying to understand them better. This stuff ain't rocket science, but there are the laws of physics and is usually pretty straight forward. I've never had much luck with my two chrony's. But getting an average velocity readings at exactly 100 yards and having your average muzzle velocity will establish your correct BC and then we can use the different drag models to better fit it to your results. Just trying to help. There are a lot of explanations for your results, but having exact numbers help. Jeff [ 08-18-2004: Message edited by: Jeff In TX ] [/QUOTE]
