with a SFP scope, if you are looking down the optical center of the scope, were the cross hairs meet or other system used, the POA and POI do not change by increasing or decreasing the power
if the SFP scope is held such as the parallax is off the optical axis, such as a ballistic hold over reticles, the hold over will move below the POI which raises the point of impact.
long range shots require more set up time, if you get it---- take it and increase the power setting
decreased FOV may make a follow up shot more difficult.
