If your velocity of 2945 was correct and you are using a 60gr v-max, you would have to have more than doubled it's BC to get that trajectory (.600 instead of it's published .265). I will assume the 2.6" sight height is correct.
I doubt that the published BC is off by much.
That leaves only a these of other possibilities:
b. Sight in distance.
You are sure of your sight in distance of 100. That leaves velocity as the only other possible to create that kind of difference. The 3250 fps velocity that was posted earlier would work.
Try some further distances to check your adjustments. I bet if you try using this much higher velocity you will find yourself getting much closer to your correct trajectory.
