A few weeks ago, I read Damon Cali's blog article demonstrating his innovative analysis method. This article contributed to my motivation to start this blog and discuss statistics applied to shooting.
He fired 175 shots on paper, and visualized the 5-shot group sizes as a contour plot to determine the optimal charge and seating depth. As you can read in his article, it is an effective way to identify the smallest group and any trends.
I thought it would benefit from a measure of statistical confidence. To rely on the results, you need to know you've fired enough shots. Further, I thought by analyzing each shot individually, rather than the ES of each 5-shot group, it might lead to some deeper insights.
I contacted him for the raw data and performed my own analysis, then wrote a guest blog article, which you can read over at his site, Bison Ballistics. In this article, I use many statistical tools to show how a deeper view of data can lead to unexpected discoveries and a more accurate load.
This opportunity presented itself so I took a short detour from my plan to show you exactly how to apply these concepts for yourself. You can look forward to that article very soon!
