Hello9 to all.
I have a Pesersoli Sharps in .45-70 caliber and is is zeroed at 100 meters.
Now I have the possobiloity to shoot at 675 meters but...but...how I ca do to st the diopter for this new distanca? There is a rule to calculate how many I have to raise the eye on diopter without wasting many cartridges?
Thanks in advance to all.
Ciao
