Thread: Trajectory calculation issue

While at the long range shoot in Kurow we had the opportunity to confirm our drop charts and collect some real data. I got the following real world results (all in yards because 1000 yards sounds way cooler than 900m) rifle is zeroed at 100m (110 yards)
343 - 4moa
480 - 8.5 moa
568 - 11.25 moa
697 - 15 moa
850 - 20 moa
5 degree angle
7mm mag firing 168gr berger vlds at 2960 fps (thats what chrony told me but 2900 seems to replicate the trajectory better)
I am using shooter and having issues getting the numbers to align to the real world results. Anyone want to join me in trying to get things to line up?
The frustrating thing is my other 2 rifles are spot on straight from shooter so think something must be wrong with the input data.
Might have to go and do another long range dady and do the data collection again to confirm but it was all pretty convincing on the day with shots landing as they should with the various corrections etc.
Wondering if maybe when we were ranging the steel targets we were actually getting readings off the ground in front/behind
Gimp did you measure the ranges to each plate from the plates at all? Did anybody else get different ranges for the plates?
