Thread: Assessing resulting vertical spread from ES (or SD) for your load at distance

Bagheera that's a good looking book, he has broken some basic information into a real world example, might have to get that one as well, any others guys could suggest.

I get the needing to zero the sight height and scope to zero in the calculator to work out ES caused by velocity as when you just change velocity the calculator alters where it thinks your sights will need to be so you arnt really seeing your true vertical spread of shots.

I think there is something here you are trying to figure out, in how the calculator works out the answer, somthing about rounding errors, I didn't catch it, it's over my head but I am interested in hearing what you find out so please put up your answers if you ever figure it out,
