[QUOTE="Michael Eichele, post: 268566, member: 1007"] 1: If youre using a second focal plane variable power scope, I would verify that you were on the appropriate setting. 2: See if you can duplicate your reults. 3: Verify your velocity. You are likely to be less than you expect. 4: You mentioned low humidity. Humidity has very little effect on a bullet. The difference between 0% and 100% is very minute even at 1K yards. You mentioned nothing of pressure. Barometric pressure even in small changes have a very drastic effect on bullet trajectory. Find an accurate pressure. This will help you find your true numbers. 5: Have you tried different drag functions?? This is most likely your issue. Try G5 and G7 over G1. One of these will likely get you closer. I use my own personaly developed software that allows me to make the drag function any number I wish. Between adjusting the drag function and BC I can match ANY real world trajectory to within an inch at any point in the range. [/QUOTE]
