- To use this to it's full potential the use of a [Vector 21]({{ site.baseurl }}/wiki/feature/vector.html) is strongly recommended, a [Kestrel 4500]({{ site.baseurl }}/wiki/feature/kestrel4500.html) will also help.
- Pull out your rangefinder ([Vector 21]({{ site.baseurl }}/wiki/feature/vector.html) preferred) and get the distance between you and your target.
- Move to the `Bullet Drop` column, the drop is in MRADs, you need to compensate for it by adjusting your sight. Example, you want to adjust for a bullet drop of -7.9 MRADs simply adjust your scope 7.9 MRADs vertically. (check [feature scopes]({{ site.baseurl }}/wiki/feature/scopes.html) ) for this.
