A few things since its not as fast as a bullet which the scope is based around its not as flat and you will have to find a happy medium just like you started to do. Play around with bc, drag and fps to get it to a spot your happy with.

I have not used mine much yet so am not totally familiar with it. Do you have to go into profiles and choose which one you want every time you turn it on or does it save the last used and just go there?

Edit;

I know I had mine set fairly well from 25 to 100 yards but I had to cheat on the BC and velocity a bit to get it there. I only had the one profile and it stayed the same and werqed well for me always shooting within a couple of inches of where it should at 100 yards. I have not got around to finishing up on the BC and velocity to make things just right as yet.

Heard you usually have to bump up your fps 30-40 or use some crazy high numbers as it doesn't have the GA profile. Check out this thread:
