So I am about to go and zero my (new to me) sako 75 .308 and Zeiss conquest scope with ballistic turrets.
I have access to a 100 meter indoor range.
My question is this.
I plan to zero my scope at 100 meters and then adjust my ballistic turret to display 0 at 100 meters.
Is it possible to use a ballistic calculator to work out the theoretical drop at say 300 meters (lets say -10cm for argument) and then mark a +10cm point on the target and adjust the ballistic turret until I hit the +10cm target so that I can record a rough point on the turrets that will be somewhere near zero at 300 meters?
I appreciate nothing is better than actually testing at various ranges though will this get me some where near to where I need to be?
