Title: power adjuster
Post by: StevenG on February 23, 2015, 08:23:01 PM

Changing the power level on my FDPCP moved the point of impact down which I expected and understand, but it also moved it to the left. It is consistent so adjusting the scope fixed it, but why would the POI move horizontally?

Barrel harmonics are the likely culprit (vibration)....
