This question may have been asked before, but if it has, I am not sure how to search for the answer, so...
I am planning to shoot in an F/TR competition next month at 500 yards, but my range here is only 300 yards, and I have no place to practice at 500 yards before the competition.
I have my rifle zeroed at 300 yards and based on the ballistics that my reloaded round is producing, I should need 30 or 31 additional clicks of elevation to be on at 500 yards.
Here's the DOPE....308 Winchester firing SMK 175 HPBT at 2550 fps; requires 22 up clicks on my scope at 300 yards. The on-line ballistics calculator says I should use 21 up clicks, so either the calculator is off by one click or my scope is off by one click. The ballistics calculator calls for 30 additional up clicks of elevation so since there is a difference of 1 click at 300, I suspect it will be the same at 500 yards and I plan to use 31 additional up clicks of elevation.
Question...is there a better way to figure this elevation adjustment?
