Four Rules of Long-Range Accuracy 1. Errors in shooting technique or wind estimation are catastrophic.
If you cannot hold well and shoot correctly, you have no chance, because there is absolutely no margin for error. A measly little twitch when you?re shooting at 100 yards will take you off the paper at 1,000.

2. He who holds off the target is lost.
I'm referring, of course, to Kentucky windage, the time-honored practice of holding high or low or right or left, depending on range and wind. Here, it?s too imprecise. There are two methods that are far better: Employ the mil dots in your reticle, or actually crank ¿¿adjustments for range and wind into your scope and hold for the center.

3. The wind will kill you.
I've seen several formulas for calculating wind drift, but try computing when you don?t know how fast the wind is moving.

4. You must be able to do math in your head as you aim the rifle.
An example: You are shooting at an elk that your range¿¿finder tells you is 760 yards away. You estimate that the wind is 10 mph where you are and 20 mph out where he is. Your rifle is zeroed dead on at either 100 or 200 yards. And your scope has mil dots instead of dial-in scope knobs. Get the picture?
