Hi everyone,

Got my hands on a chronograph yesterday to test some new loads. One of the features that it gives is Standard Deviation. Most of my 10 shot strings for most of my loads fell between 12.8 - 3.1 standard deviation. Im not sure what this means. Can anyone help????

Thanks!!!

ps: the chrono i used was a friends Competition electronics with the infrared setup. worked flawlessly, even with rapid fire strings!!!!
