Like centrefire at 200 yards?
About 1/2 a degree of downslope required on the scope?
Yep about that.
Working in metric 'cos numbers are rounder that's 300mm give or take.
High mounted scope 50mm above bore, so vertical displacement sight line to target = 350mm
50m range so horizontal displacement = 50,000 mm
Let angle be x
tan(x)=350/50000
x = atan(0.007) = 0.4 deg (24 MOA)
