Please don't laugh guy's
went shooting with my nightforce I always tough
that .25 moa meant 1/4 inche
made myself a target with 5 different aiming point so I could check if the ballistic chart from JBM to 500 hundred yards was OK,
well nothing worked...
could you explain to me exactly what is a MOA in length and when they say on JBM to crank up let say
7.7 MOA you dial up the 7 mark on the elevation turret and the .7 there is only 4 graduation bar between each number so do you have to make a calculation each time and for the .7 dial 3 click or is there a way on the JBM site to come with 4 bar setting?
thank you Michel


 
Re: just found out my scope was MOA

The difference is about 5%.

MOAs move the impact MORE at 100 YARDS by that amount. More precisely, it's 1.0471975511966 inches per MOA, or 0.26179938779915 inch per 1/4-MOA click.

It generally doesn't become too important inside of 300 yards.
