Where you say the aim points are "as they should be" according to who/what exactly ??
If you are comparing them to your previous scope then it's just showing the difference between the two sets of glass.
If the MV is identical the same pellet should follow the same tragectory, obviously if the stripper has effected the MV the tragectory will change.
A head/tail wind or rain in the air will also effect a pellets tragectory.
