okay, im still trying to figure this whole thing out. If I sight my gun in at 100 yds, and im shooting,say, 21 inches low at 400 yds, i would turn my scope up 2.1 MOA. That would be 8 or 9 clicks with a scope with a 1/4 moa right?
Moving the decimal point two places does the same as dividing by 100, no math involved, and I'm sure Dave does this in his head too. But, dividing by 100 shows what you are really doing.
If your shot was at 1000 yards, or 10 times as far, your inches divided by 10 like you did would be correct. You were only shooting 4 times as far, so you'd divide by 4.
680 yards would be 6.80 times as far, so you'd divide the inches by 6.8.
thanks. hows this, the distance is 564 yards, im 32 inches low. I divide 564 by 100. Then i divide 32 by 5.64 and get 5.67, so id have to adjust 5.67 moa, which is like 22 or 23 clicks. Is that right?
To get a more accurate way of knowing what your drop is, shoot your rifle through a chronograph and take your average velocity, and plug it into the formula in a bullet path chart like sierras infinity program. This will tell you everything you want to know and how many moa to put on that deer at 750. It also saves alot of wear on your barrel instead of testing every yardage to find out what your drop is.
