Range Report spin drift figures

Re: spin drift figures

yeah but it involves accounting for lunar drift, the rise and fall of the tides, what the weather is like in Asia at the time as well, and dont forget to account for the Coreolis effect.

But in a simple way, when running your JBM calculations, click the box that say Spin Drift and enter your info and blammmmm there you have it. But its a null and void. My spin drift at 1K for my 260 is like .19 mils...that may sound alot, but you cant read the wind to that accurate to blow your shoot due to spin drift.
 
Re: spin drift figures

If you are looking for the actual maths, then I can lend some assistance. But before I start, like HDC said, JBM will give you spin drift. All the equations and descriptions of needed quantities are given below.
