This video tutorial shows the process of using JBM ballistics to calculate the drop data needed to fill in our ballistic table templates. There are many different ballistic software programs out there that do a great job at calculating these things, so please feel free to use which ever software you are most satisfied with. These templates are designed to give you that flexibility to plug in what you want. JBM ballistics is a very good program that I recommend for the purposes of this shooting discipline. Although I have developed similar programs using Excel for my own purposes, adjusting the various inputs and parameters for your chosen output units (meters/MOA/MRADs, etc...) has proven exceedingly difficult and is not near as flexible as this system. Pasting the information into the templates (as shown in this video) from JBM ballistics or any other appropriate programs will yield the best results and will be much easier to do. If you try this long-hand, you may wish to die. NOTE: Your calculated ballistic data will only be as precise as the inputs you enter into the program. Be sure to triple check all of your inputs before calculating. Pay special attention to your MVs at the various temperatures. Logging your MV variation at different ammunition temperatures is a CRUCIAL component in getting good data back from this or any other software. Actual MVs in any rifle change over time due to a number of factors. Be sure to keep an eye on your MVs. Much more to come! Stay tuned and share this with your friends! Here are the TEMPLATE links: when you open these, click on the downward pointing arrow button on the upper left side to open the adjustable Excel sheet.
