Finding your Speed Drop Factor

How long does it take to find our drop data for a target range? If we need data quickly, most shooters are using some type of paper chart. This chart could be taped to the stock, on a data holder, or arm bar where with a quick glance we can read our data. What if there is a faster way? Welcome to the Speed Drop Factor. Finding and using your Speed Drop Factor will allow you to memorize your drop data to a reasonable distance by remembering one number.
