[QUOTE="dougduey, post: 1696507, member: 33159"] So, an update on why the BC for the 6.5 Bergers 140 gr VLD was so off. I had my follow up long range shooting class today. It was the field course, in which I was shooting from all sorts of improvised positions (450-1079 yards). The adjusted BC for the Berger was spot on today. After we finished with the field course, the instructor said he wanted to do a tracking test on a tall target to see if my scope was the issue and not the bullet BC. He shot a group at exactly 100 yards, then dialed up 20 moa and shot another group. Then he grabbed the target and measured the distance between the 2 groups. It should have been 20” but it was 21.25”!! That’s a 6% error. When we plugged the data into the ballistics calculator to adjust for the error and put the BC back to what it says on the Berger bullet box, it all lined up. I shot targets out past 700 yards to validate everything, and it was dead on. If I never shot this rifle past 500 yards, I honestly would have never known I had an issue. I’m glad my instructor had a hunch and decided to see if it was the issue. Now I have to contact Zeiss and see how they’re going to handle it. This is one of the new Zeiss V6 5-30x models. I love the glass on it, so I hope they’re customer service is good. So much for using this rifle on a NM pronghorn hunt this coming weekend. Luckily I have other rifles that want to go hunting!!
