Same problem here.
New P15 5.5mm (did 400 shot)
Steady 850 fps from 230 to 130 bar.
Using jsb exact jumbo 18.13g (washed, sorted in groups)
Tried 2 scopes.
VTZ 4-16x50 FFP
EDL 5-40X56 FFP
Did:
Bore/scope mirror leveling
Bubble leveling (both rail + scopes)
Bob plumb line (reticle horizontally adjusted at 7 meters and 90 meters wall)
Zero at 30 meters.
Shooting at 90 meters:
1) Straight line of sight Shooting - POI is minus 2 mil or minus 2.5 mil.
2) Shooting 5 meters to the left - POI dropping to minus 3.5 mildot and drifting 3 mildot to the left.
3) Shooting 5 metets to the right - POI dropping to minus 3 mildot and drifting 2 mildot to the right.
I always shoot at 90 meters to adjust my POI.
Dunno what's wrong maybe someone can explain thank you.
